TELSMITH FEEDERS

Telsmith Feeders are used for holding and regulating surgeloads and to promote a steady supply to maximizeproduction in processing plants. These feeders are offeredin four types to match material size, feed rate requirements,location and if fed from truck, shovel, loader, or mountedunder a surge bin.

6

DATA REQUIRED FOR SELECTING A FEEDER

1. Tons per hour to be handled, including maximum and minimum.

2. Weight per cubic foot (bulk density) of the material.

3. Distance material is to be conveyed.

4. Height material is to be raised.

5. Space limitations.

6. Method of loading feeder.

7. Characteristics of material.

8. Type of machine to be fed.

PROCEDURE FOR SELECTING A FEEDER

STEP 1. Select a type of feeder from Table 1, Page 7.

STEP 2. Select feeder width. The width may be dictated bythe machine to be fed, i.e., a jaw crusher with acertain receiving opening, or by the size of the hopperopening to be used. Feeder width may also bedetermined by the maximum lump size in the feed, orby a desired depth of material and conveying speed.*†

STEP 3. Check capacity of feeder selected against the datain Tables 2A, B, C & D, pages 7 thru 10.

STEP 4. Determine HP required from Tables in Section forFeeder selected in STEP 1.

* depth of 100 lbs./ ft.3 material may be found by:

D = depth in inches

TPH = tons per hour

FPM = feet per minute material is moved

W = net width of feeder in inches

† Do not use the above chart for Belt Feeder capacities.

D = 50 × TPHw × FPM

APRON FEEDERS

Apron feeders are used where extremely rugged machineshandling large feed are required, but where no fines removalis needed or where fines are removed by a separateVibrating Grizzly (see Pages 136—138). They are also usedto handle muddy or sticky material. Normally located aheadof large, stationary primary crushers. They are sometimesused to collect material from the discharge of very largeprimary crushers where they absorb more impact than arubber conveyor belt can economically withstand. TheseApron Feeders can be equipped with standard(1/2" thick) fabricated pans (standard and heavy dutyFeeders) or optional (11/4" thick) fabricated pans (XHDFeeders only). They are available in widths of 30" to 72"and lengths of 9' to 50'. For more information, see BulletinAF 102.

HORSEPOWER OF APRON FEEDERS

Total horsepower is calculated using the following formulas.

L = C/L to C/L of sprockets

W= Width in feet inside skirt boards

H = Height in feet of material bed1/2 Pan Width = Normal2/3 Pan Width = Maximum

s = 0.8 Slip Factor = Inclines = 0.9 Slip Factor = Horizontal

M = Wt. per Ft.3 of Material

S = Speed in FPM

Total Load of Material = L × H × W × M

VIBRATING FEEDERS ANDVIBRATING GRIZZLY FEEDERS

Vibrating Feeders are used where a compact feeder withvariable speed control is required. Vibrating Grizzly Feedershave features similar to the Vibrating Feeder plus grizzly barsfor separating fines from crusher feed. This feeder increasescrushing plant production and reduces crusher liner wearbecause fines are bypassed around the primary crusher.

Both feeders are available in widths from 36" through 72"and 12' through 30' long. Grizzly sections are straight orstepped. The stepped version tumbles stone to the lowersection thus offering more efficient scalping. For fulldescription and illustrations, refer to Bulletin T301.

CRUSHERS

GENERAL NOTES ON CRUSHER SECTION

1. To secure the capacities specified, all feed to crushers shouldbe smaller than the feed opening of the crusher in at leastone dimension.

2. The horsepower required varies with the size of product beingmade, the capacity and the toughness of the rock or ore.

3. The capacities given are in tons of 2,000 lbs. and are basedon crushing limestone weighing loose about 2,700 lbs. peryard3 and having a specific gravity of 2.6. Wet, sticky andextremely hard or tough feeds will tend to reduce crushercapacities.

4. No crusher, when set at any given discharge opening, willmake a product all of which will pass a screen opening of thesame dimensions as the given discharge opening.

The crusher discharge opening is measured asfollows:

Graysphere — closed sideJaw Crusher — when jaws are in closed positionfrom peak to peakGyratory Breaker — open sideIntercone — closed side

For close settings, all undersize material should beremoved from the feed so as to eliminate packing andexcessive wear.

5. Where no rating is specified in the capacity table for anycertain discharge opening, the crusher cannot be operatedeconomically at that opening. For a setting finer than theminimum, consult factory.

6. The minimum settings indicated for crushers is not necessarilyapplicable for each and every application.

NOTE ON CAPACITIES: All capacities shown are approximateand will vary with the physical properties of material, moisturecontent, feed method, and amount of fines.

19

JAW CRUSHER DISCHARGE SETTINGS

“X” dimension equals Peak-To-Peak measurement.

To set the Closed Side Discharge Setting, use a wood blockwith the same width as the desired setting. It should be longenough to span most of the crusher's discharge area. Thedischarge setting is gauged with the opening in its closestposition of the operating stroke.

X

GYRASPHERE CRUSHER DISCHARGE SETTINGS

“X” dimension equals Closed Side Discharge Opening.

To determine the Closed Side Setting (CSS) of a GyrasphereCrusher lower, on a wire or heavy string, into the open side of thecrushing chamber, a ball of clay or aluminum foil larger than thedischarge chamber until the ball is at the lowest area of thecrushing chamber. Hold the crusher’s head and rotate the crusherdrive until the ball has been compressed at least twice. Thethickness of the ball at its thinnest dimension equals the CSS.

On crushers equipped with anti-spin, drop the clay ball or aluminumfoil into the crushing chamber while the crusher is running.

Typical examples showing how to determine the size ofvibrating screen required for a certain capacity or to

determine the capacity of any size of vibrating screen.

EXAMPLE NO. 1

To determine the capacity in TPH that can be passed through a 3' × 8'vibrating screen under the following conditions:—1. The material to be screened is ordinary gravel.2. Screen cloth having 1" square opening.3. 30% of the material to be screened is larger than 1" or there is 30%

of oversize.4. Desired screening efficiency 90%.5. 50% of the material to be screened is less than one-half the size of

the screen opening. In other words, one-half of the material to bescreened is less than 1/2" in size.

6. Screening will be done dry, or as the gravel comes from the bank.No water will be used.

7. A single deck vibrating screen will be used.Referring to the capacity and factor tables on Pages 116—119,

we select the following factors:—Factor “A”: — Gravel with 1" square opening—3.36.Factor “B”: — 30% of oversize—.96.Factor “C”: — 90% efficiency—1.15.Factor “D”: — 50% less than one-half size of opening—1.20.

* Factor “E”: — Dry screening—1.00.Factor “F”: — Single deck screen (top deck)—1.00.

The solution, in accordance with formula No. 1, is the area of the screencloth multiplied by all of the above factors or 3'×8'=24 sq. ft. of area×3.36×.96×1.15×1.20×1.00×1.00=107 tons per hour.

107 tons per hour is the capacity passing through the 1" holes of thescreen, and is 70% of the feed to the screen. 30% of the feed was rejectedby the 1" holes. The total capacity that can be handled by the screen is thesum of these two or 153 tons per hour.

*Note:—For wet screening, change this factor as shown in table underFactor “E”. Same applies in Examples 2 and 3.

EXAMPLE NO. 2

To determine the size of the vibrating screen required under the followingconditions:—1. The material to be screened is crushed stone.2. Screen cloth having 11/4" square openings.3. Total capacity required — 60 tons per hour.4. 25% of the material to be screened is larger than 11/4".5. Desired screening efficiency 92%.6. 20% of the stone is less than 1/2 the size of the 11/4" openings.7. The stone will be screened dry.8. A single deck vibrating screen will be used.

Continued on next page

CAPACITY OF VIBRATING SCREENS (Cont.)

121

Referring to the capacity and factor tables on Pages 116—119, we selectthe following factors:—Factor “A”: — 2.95.Factor “B”: — .99.Factor “C”: — 1.08.Factor “D”: — .60.

* Factor “E”: — 1.00.Factor “F”: — 1.00.

The solution, in accordance with formula No. 3, is as follows: — 60 TPHless 25% of 60 or 15 TPH gives 45 TPH divided by (2.95 × .99 × 1.08 ×.60 × 1.00 × 1.00) = 23.8 ft.2 of screen surface. A 3'×8' screen is thecorrect size.

CAPACITY OF VIBRATING SCREENS (Cont.)

EXAMPLE NO. 3

To determine the size of a double deck screen under the following conditions:—1. The material to be screened is crushed stone.2. Capacity to be handled is 80 tons per hour.3. Square openings in top deck are 1".4. Square openings in bottom deck are 1/4".5. 20% of the 80 TPH is over 1" in size.6. An efficiency of 96% is required.7. 40% of the material is less than one-half the size of the top deck or 1"

openings.8. There is 15% of minus 1/4" material to be taken out through the

bottom deck; and of this 1/4" material, 10% is less than one-half thesize of the 1/4" opening.

9. The oversize from the top deck is to be recrushed to minus 1" andreturned to the screen.

A problem of this kind must be treated as two separatecomputations, one for the top deck and one for the bottom deck.The solution is as follows:—

screen surface required for the top deck = 3'×10' vibrating screenConsidering the lower deck, we find that 15% of the total of 80

TPH must pass through the bottom deck or 12 TPH must passthrough the 1/4" openings. This makes 85% of oversize on thebottom deck. Using formula No. 3 and factors again, we have thefollowing for the bottom deck:—

of screen surface required for the bottom deck = about 4'×8' screenIn problems like Example 3, especially where the bottom deck has

a fairly small opening, it will usually be found that the size of thebottom deck determines the size of the screen. In a case of thiskind where one deck requires a larger area than the other, alwaysselect a screen or screens which will give the larger area for bothdecks.

Area = 80TPH = 80TPH = 29.7 = No. of Sq. Ft.A×B×C×D×E×F 2.78×1.02×.95×1.00×1.00×1.00

Area = 12TPH = 12TPH = 29.7 = No. of Sq. Ft.A×B×C×D×E×F 1.74×.50×.95×.5×1.00×.90

NOTES: Wire diameters listed above are suitable for feed size not exceedingthat listed in Column I. When feed size exceeds Column I but not Column II,use next larger wire diameter. When it exceeds Column II but not Column III,increase wire diameter two sizes. Wet Screen: Select next larger wirediameter. Perforated Plate is recommended for openings larger than 4".1/2" diameter and smaller wire furnished with hooked edges as standard andfor side tension bars. Larger than 1/2" diameter wire requires flat supporttray and clamping strips. New screens normally furnished with wirediameters as listed in Column C, medium heavy wire, for top deck; andlower deck surfaces with medium wire Column B. Spring steel cloth isstandard. Oil tempered, stainless steel, profile wire, or rubber deck surfacesare optional extras — Consult Factory.

A typical example of open area correction to screen is:50% (Mentioned in “A” Factor) ÷ the open area percentage = thepercentage to be multiplied by the square footage of screen area.Calculation: .50/.58 = 86%×190 ft.2 = reduced area to 163 ft.2

(58% open area was derived by 1" clear ft.2 opening, “C” medium heavy wire .3125)

DEWATERING & CLASSIFYING TANKS

Used to recover sand from large volumes of water throughsettling, these units are indispensible in aggregate washingoperations. Telsmith Dewatering and Classifying Tanks arebuilt in 8' widths for average water flows in 20' to 32'lengths, 10' widths for greater capacity and water volumesin 24' to 40' lengths, and 12' × 48' size for maximumcapacity; these tanks are designed to separate the sandinto various particle sizes through the use of multipledischarge valves and multi-compartment flumes. Accuratespecification sands can be produced using these tanks.For full description and illustrations, refer to Bulletin T-800.

To determine the GPM of water in the overflow of a sand classifieror sand tank, take measurement “H” in inches at a point severalinches back from the crest. For example, if the water is about 2"deep at the crest, take a measurement about 6" to 8" back fromthe crest and from the surface of the water down to the horizontalline “A-A” securing depth of overflow “H”. Using table, determiningGPM for weir 1 ft. wide and multiply this by width of overflow in feet.

CYCLONE CLASSIFIERS

These fine sand reclaiming units have no moving parts. Theyoperate on the principle of centrifugal force. This force, introducedby the slurry in-flow separates the coarser fractions from the non-desired fines. They normally separate at the 150 mesh size range.In operations where minus 30 mesh sand is in short supply theycan significantly increase plant capacity of specification materials.For a full description, refer to Bulletin T-800.

152

SAND RECOVERY WITH THE TELSMITH CYCLONE

The Telsmith Cyclone recovers fine sand in the 30-200 meshsize range to increase sand recovery capacity and restores thosefine sizes needed to meet present day sand specifications. Thispremium sand, formerly discharged into water settling basinswhere frequent removal is necessary, becomes a source of incomerather than an expense.

FAST PARTICLE AND FLUID DISTRIBUTION

A three-way flow speeds particle separation. Powerful entry flowsets up secondary flows in the feed and cone sections to movewaste upward through the vortex and out the top overflow. Theboundary wall flow, through centrifugal force releases recoverysand through bottom discharge valve.

COARSE MATERIAL WASHERS

Coarse Material Washers are used to wash coarse sand orcrushed stone and gravel with a maximum size of 21/2" andto dewater the cleaned material sufficiently so it can beconveyed to storage. They are also used, in someinstallations to assist with the removal of lignite, mica, bark,leaves and trash. They are manufactured in single and doublespiral configurations with spiral diameters of 24" to 48" andtank lengths of 15'-0" to 23'-3". For more information, seeBulletin ATP K-Sand-01.

LOG WASHERS

Log washers consist of a variably inclined tub with twocounter-rotating “logs”. Each log has four (4) rows ofpaddles which overlap (log-to-log) to create the scrubbingaction required. The primary purpose of the log washer isto remove tough, plastic soluble clays from natural andcrushed gravel, crushed stone and ore feeds. It will alsoremove coatings from individual particles, break upagglomerations, and reduce some soft fractions by a mildform of differential grinding. Log washers are available insizes of 24", 36" and 48" diameter sizes. For moreinformation, see Bulletin ATP K-Sand-01.

BELT CONVEYORS

Belt Conveyors are available in a complete range of typesand sizes to suit every material handling requirement.Standard and specially engineered units and variouscombinations of both, permit engineers to select the systembest suited to a particular job from the industries broadselection of conveyor components and accessories.

Every component is backed by more than a half century ofexperience in the design and manufacture of materialshandling equipment.

By purchasing both materials handling and processingequipment from the same manufacturer, the buyer isassured of greatest efficiency and economy from single-source responsibility for design, manufacture, erection andproper operation of the entire plant. The resulting balanceddesign eliminates bottlenecks and assures peak capacityand efficiency from every unit in the system.

MAXIMUM BELT CAPACITIES

1 All capacities shown are for material weighing 100 lbs.per ft.3 and moving on belt at 100 fpm. For other weights,capacity equals table capacity

For other belt speeds, capacity equals table capacity(or calculated capacity)

2 The surcharge angle is the angleformed between a horizontal line and aline tangent to the material’s slope,both of which lines pass through thepoint where the slope meets the belt.Usually the surcharge angle is 10°-15°less than the angle of repose. Seesketch at right.

3 “Mixed with 50% fines” means at least half of the material must beless than one-half the maximum material size.

SELECTING IDLERSNUMBER OF IDLERS REQUIRED

To determine the number of troughing idlers required for aconveyor, follow this formula: Divide the length of the conveyor(in feet) by the idler spacing (in feet — see Table below), andsubtract one. Then add two idlers for each loading point. Fortail-loading points, mount one flat idler at the back of the loadinghopper to prevent spillage.

For return idlers, divide the length of the conveyor (in feet) bythe return idler spacing (in feet — see Table below), and subtractone.

Example: Determine the number of troughing and returnidlers required for the following conveyor:30" width × 402'-0" centersRecommended idler spacing — 4'-0"One loading point, at conveyor tail endNumber of Troughing Idlers:

103 Troughing Idlers:

VOLUME OF ELONGATED OR TENT-SHAPEDSTOCKPILES

Determining the volume of an elongated stockpile becomesreadily apparent by separating the pile into its two basic forms,a conical pile and a prism-shaped pile. (See Figure 2.) From thechart on Page 171, find the volume and dimensions of theconical pile which is equivalent to the two ends, and to this addthe volume of the prism-shaped center section.

EXAMPLE

An area 120' wide and 415' long is available for an elongatedstockpile. What volume can be stockpiled if the material has a37° angle of repose?

1. From the chart, we find the conical pile in the precedingexample is equivalent to the ends of this tent-shapedpile and, therefore, the volume is 6224 yds3.

2. Subtract width of the conical pile from overall pilelength to determine the length of prism-shaped section.

3. Find the volume of prism by:

4. Since there are 27 ft3 per yd3, divide:

5. Add the volume of ends and prism:

420–120

= 300

W = LENGTH×WIDTH×HEIGHT=

300 ft.×120 ft.×45ft.= 720,000 ft3

720,000 ft3 = 26,677 yd3 (Prism volume)27 ft3/yd3

AGGREGATE is made up of inert material such as sand andgravel, crushed stone or slag, which when bound together into aconglomerated mass by a matrix forms concretes, mortars, plasterand mastics such as black top or macadam roads and asphaltroad surfaces.

SAND is a finer granular material (usually lass than 1/4" india.) resulting from the natural disintegration of rock or from thecrushing of friable sandstone rock or other suitable rocks.

GRAVEL is a coarse granular material (usually larger than 1/4" india.) resulting from the natural erosion and disintegration of rock.

CRUSHED GRAVEL is the product resulting from the artificialcrushing of gravel with most all fragments having at least oneface resulting from fracture.

CRUSHED STONE is the product resulting from the artificialcrushing of rocks, boulders or large cobblestones with thefragments having all faces resulting from the crushing operation.

ROCK, from which crushed stone, sand and gravel are madeand the rock most suitable for making good aggregates is formedall over the world. See page 188 for the various kinds of rocksand their physical properties.

SLAG is the air-cooled, non-metallic by-product of a blastfurnace operation consisting essentially of silicates and alumina-sil icates of l ime and other bases which is developedsimultaneously with iron in a blast furnace. Naturally, it is onlyavailable in those localities where pig iron is produced. Crushedslag weighs about 80 lbs. per ft3.

The value of rock for road building depends largely upon theextent to which it will resist the destructive influences of trafficand the weather. The most important physical properties arehardness, toughness and soundness. Hardness is the resistancewhich the rock offers to the displacement of its surface particlesby abrasion, toughness is the resistance which it offers to fractureunder impact, and soundness is the resistance offered to theeffects of weathering. The hardness of a rock is determined bythe Los Angeles Abrasion test, the Dorry hardness test and theDeval Abrasion test. The abrasion tests are also a measure of thetoughness of rock and supplement in this respect the impact testfor toughness.

If the rock, sand and gravel or other material which theaggregate producer proposes to process, passes all of therequired State Highway Department tests satisfactorily, and isavailable in sufficient quantity to warrant the installation of a quarryor gravel plant, this aggregate producers data book gives up-to-date information on the size and type of equipment most generallyused for crushing, screening and processing. Be sure to consultyour State Highway Department for aggregate specifications.

STANDARD DESCRIPTIVE NOMENCLATURE OFCONSTITUENTS OF NATURAL MINERAL

AGGREGATESThe purpose of this nomenclature is to provide brief, useful and accurate

descriptions of some of the more common or more important naturalmaterials found as constituents of mineral aggregates. These descriptionsare for minerals and rocks as they occur in nature only, and do not includeblast-furnace slag or lightweight aggregates which are prepared by thealteration of the structure of a natural material. The descriptions have beenprepared to provide a basis for understanding these terms when they areused to designate aggregate constituents. It should be emphasized thatmany of the materials described frequently occur in particles that do notdisplay all of the characteristics given in the descriptions and that most ofthese materials grade from varieties meeting one description to varietiesmeeting another, with all intermediate stages being found.

These descriptions are not adequate to permit the identification ofmaterials, since the accurate identification of the natural constituents ofmineral aggregates can, in many cases, only be made by a qualifiedgeologist, mineralogist or petrographer using the apparatus and proceduresof these sciences. Reference to these descriptions may, however, serve toindicate or prevent gross errors in identification. Identification of theconstituent materials in a mineral aggregate may assist in recognizing itsproperties, but identification alone, however accurately it may beaccomplished, cannot provide a basis for predicting the behavior ofaggregates in service. Mineral aggregates composed of constituents ofany type or combination of types may perform well or poorly in servicedepending upon the exposure to which they are subjected, the physicaland chemical properties of the matrix in which they are embedded, theirphysical condition at the time they are used, and upon other factors.

The natural materials found as constituents of mineral aggregates are,for the most part, particles of rocks and minerals. Rocks are classifiedaccording to origin into three major groups: igneous, sedimentary andmetamorphic; and are subdivided into types according to mineral andchemical composition, texture and structure. Most rock particles arecomposed of mineral grains of more than one type. However, in somecases, a rock may be composed of grains of only one mineral. Certainexamples of the rock quartzite are composed exclusively of the mineralquartz. The particles composing the finer sizes of many sands frequentlyconsist of individual mineral grains. Descriptions are, therefore, given notonly of rock types but also of minerals.Silica Minerals

1. (a) QUARTZ — Quartz is a hard mineral (will scratch glass and not bescratched by a knife) composed wholly of silica (silicon dioxide). Whenpure it is colorless with a glassy (vitreous) luster and a shell-like (conchoidal)fracture. It lacks a visible cleavage, and, when present in massive rockssuch as granite, it usually has no characteristic shape.

(b) OPAL — Opal is a hydrous form of silica which occurs as anamorphous mineral and, therefore, is without characteristic external shapeor internal crystalline arrangement. It has variable water content rangingfrom 2% to 10%. The specific gravity and hardness are always less thanthose of quartz. The color is variable and the luster is resinous to glassy. Itis usually found in sedimentary rocks and is the principal constituent ofdiatomite, but it is also found as a secondary material filling cavities andfissures in igneous rocks. It is of particular importance as a constituent ofmineral aggregates because of its reactivity with the alkalies in portlandcement.

183

(c) CHALCEDONY — Chalcedony has been considered both as adistinct mineral and as a variety of quartz. It is now generally believed to becomposed of a submicroscopic mixture of fibrous quartz with a smallerbut variable amount of opal. The properties of chalcedony are intermediatebetween those of opal and quartz, from which it can be distinguished onlyby laboratory tests. It frequently occurs as a constituent of the rock chertand is reactive with the alkalies in portland cement.

(d) TRIDYMITE AND CRISTOBALITE — These minerals are crystallineforms of silica which are sometimes found in volcanic igneous rocks. Theyare metastable at ordinary temperatures and pressures. Unless they occurin well-shaped crystals, they can only be distinguished from quartz bylaboratory tests. They are rare minerals and are included here only becauseof their reactivity with cement alkalies.Feldspars

2. The minerals of the feldspar group are the most abundant rock-formingminerals. Since all feldspars have good cleavage in two directions, particlesof feldspar usually show several smooth surfaces. Frequently, the smoothcleavage surfaces show fine parallel lines. All feldspars are softer than,and can be scratched by, quartz. The various members of the group aredifferentiated by chemical composition and crystallographic properties.The potash feldspars orthoclase, sanidine and microcline are silicates ofaluminum and potassium, and are frequently referred to as the “potash” orpotassium feldspars. The plagioclase feldspars include those that aresilicates of aluminum and sodium, aluminum and calcium, or aluminum andboth sodium and calcium. This group is frequently referred to as the “soda-lime” group and includes a continuous series, of varying chemicalcomposition, from albite, the aluminum-sodium feldspar, to anorthite, thealuminum-calcium feldspar, with intermediate members of the seriesdesignated oligoclase, andesine, labradorite and bytownite. Feldsparscontaining potassium or sodium occur typically in granite and rhyolitic rocks,whereas those of higher calcium content are found in rocks of lower silicacontent such as diorite, gabbro, andesite and basalt.Micaceous Minerals

3. The micaceous minerals characteristically have a perfect cleavage.Particles of such minerals can, therefore, usually be split into extremelythin flakes. The true micas are usually colorless or light green (muscovite);or dark green, dark brown, to black (biotite), and have elastic flakes. Thegreen micaceous material often found in schists usually represents mineralsof the chlorite group which may be distinguished from the micas becausethey form comparatively nonelastic flakes.Carbonate Minerals

4. The most common carbonate mineral is calcite (calcium carbonate).The mineral dolomite consists of calcium carbonate and magnesiumcarbonate in equivalent chemical amounts, which are 54.27% and 45.73%by weight, respectively. Both calcite and dolomite are relatively soft, thehardness of calcite being 3 and that of dolomite 31/2 to 4 on the Mohsscale, and are readily scratched by a knife blade. They have rhombohedralcleavage which results in their breaking into fragments with smoothparallelogram-shaped sides. Calcite is soluble with effervescence in colddilute hydrochloric acid; dolomite is soluble with effervescence only if theacid or the sample is heated or if the sample is pulverized.Ferromagnesian Minerals

5. The various types of igneous rocks contain characteristic dark greento black minerals. These are generally silicates of iron or magnesium, orboth, and include the minerals of the amphibole and pyroxene groups. Themost common amphibole is hornblende; the most common pyroxene isaugite. Black mica, biotite, may also be considered as a ferromagnesianmineral. Amphiboles, pyroxenes, and biotite may also be found in marble.

184

Olivine, usually olive-green in color, is a characteristic mineral of igneousrocks of very low silica content.Clay Minerals

6. The term “clay” refers to a rock or other natural material composedof particles of a specific size range, and containing appreciable quantitiesof clay minerals (hydrosilicates of aluminum, or magnesium, or both). Clayminerals generally are formed by the alteration of feldspars, other silicateminerals, and volcanic glass. Most particles consisting of clay mineralsare soft and porous, and some clay minerals of the montmorillonite andillite (hydromica) groups (swelling clays) undergo large volume changewith wetting and drying. Clay minerals are found in seams and pockets oflimestones, disseminated through limestones and other sedimentary rocksin weathered igneous rocks and are important constituents of shales.Sulfides

7. Many sulfide minerals are important ores of metals, but only pyriteand marcasite, both sulfides of iron, are frequently found in mineralaggregates. Pyrite is found in igneous, sedimentary, and metamorphicrocks; marcasite is much less common and is found mainly in sedimentaryrocks. Pyrite is brass yellow in color and has a metallic luster; marcasite isalso metallic but lighter in color. Pyrite is often found in cubic crystals.Marcasite often oxidizes with the liberation of sulfuric acid and formationof iron oxides and hydroxides and, to a much lesser extent, sulfates; pyritedoes so less readily. Both minerals are known as “fool’s gold.”Iron Oxides

8. The common iron oxide minerals may be grouped in three classes:(1) Black, magnetic: magnetite; (2) Red or reddish when powdered:

hematite; (3) Brown or yellowish: limonite. Magnetite is an importantaccessory mineral in many dark igneous rocks. Limonite is a term appliedloosely to a variety of brown or yellowish minerals, some of which arehydrous and include the iron minerals in many ferruginous sandstones,shales, and clay ironstones.Zeolites:

9. The zeolite minerals comprise a large group of soft, hydrous silicatesusually white or light colored, formed as a secondary filling in cavities orfissures in rocks. Some zeolites, particularly laumontite, natrolite, andheulandite, are reported to have produced deleterious effects in concrete,the latter two having been reported to be reactive with cement alkalies.DESCRIPTIONS OF IGNEOUS ROCKS

10. Igneous rocks are those that have been formed by cooling from amolten mass. They may be divided into two classes: (1) Coarse-Grained(intrusive, deep-seated), and (2) Fine-grained (shallow-intrusive, extrusivesurface, volcanic) rocks. The coarse-grained rocks cooled slowly withinthe earth. The fine-grained rocks formed as rather quickly cooled lavasand frequently contain natural glass. The porphyries are characterized bythe presence of large mineral grains in a fine-grained groundmass. Thistexture is the result of a sharp change in the rate of cooling or otherphysicochemical conditions during the solidification of the rock.

Within the two classes, rocks are usually classified and named on thebasis of their mineral content, which in turn depends to a large extent onthe chemical composition. Rocks in the intrusive class generally havechemical equivalents in the extrusive class.


AGGREGATES (Cont.)

185

Coarse-Grained Intrusive Igneous Rocks11. (a) GRANITE. — Granite is a medium-to coarse-grained, light-colored

rock characterized by the presence of quartz and feldspar. Thecharacteristic feldspars are orthoclase, microcline, or albite. Feldspar isusually more abundant than quartz. Dark-colored mica (biotite) is usuallypresent and light-colored mica (muscovite) frequently. Other dark-coloredminerals, especially hornblende, may be present in amounts less than thoseof the light-colored constituents. Quartz-monzonite and granodiorite maybe mentioned as rocks similar to granite, but containing more plagioclasefeldspar.

(b) SYENITE. — Syenite is a medium-to coarse-grained, light-coloredrock composed essentially of feldspar, generally orthoclase. Quartz isgenerally absent. Dark ferromagnesian minerals such as hornblende,biotite, or pyroxene may be present.

(c) DIORITE. — Diorite is a medium-to coarse-grained rock composedessentially of plagioclase feldspar and one or more ferromagnesian mineralssuch as hornblende, biotite, or pyroxene. The plagioclase is intermediatein composition, usually of the variety known as andesine. Diorite is darkerin color than granite or syenite and lighter than gabbro. If quartz is present,the rock is called quartz diorite.

(d) GABBRO. — Gabbro is a medium-to coarse-grained, dark-coloredrock consisting essentially of ferromagnesian minerals and plagioclasefeldspar. The ferromagnesian minerals may be pyroxenes, amphiboles, orboth. The plagioclase is one of the calcium-rich varieties such as labradorite.Ferromagnesian minerals are usually more abundant than feldspar. Diabaseis rock of similar composition to gabbro and basalt but is intermediate inmode of origin, usually occurring in smaller intrusions than gabbro, andhaving a medium-grained texture. The term “trap” or “trap rock” is acollective term for dark-colored, fine- to medium-grained igneous rockssuch as diabase and basalt.

(e)PYROXENITE AND PERIDOTITE. — Rocks composed almost entirelyof olivine or of both olivine and pyroxene are known as peridotites.Pyroxenites are composed almost entirely of pyroxene.

Rocks of these types are relatively rare but their metamorphosedequivalent, serpentine, is more common.

(f) PEGMATITE. — Extremely coarse-grained varieties of igneous rocksare known as pegmatites. These are usually light colored and are generallyequivalent to granite or syenite.Fine-Grained Extrusive Igneous Rocks

12. The fine-grained equivalents of the coarse-grained igneous rocksdescribed above have similar chemical compositions. The extrusive rocksare so fine-grained that the individual mineral grains are usually not visibleto the naked eye. They may contain the same constituent minerals, or therocks may be partially or wholly glassy.

(a) OBSIDIAN, PUMICE, AND PERLITE. — Igneous rocks composedwholly of glass have been named on the basis of their texture. A densenatural glass is called obsidian, while a glassy froth filled with bubbles iscalled pumice. A siliceous or glassy lava with an onion-like structure anda pearly luster, containing 2% to 5% water, is called perlite. When heatedquickly to the softening temperature, perlite puffs to become an artificialpumice. These rocks may be reactive with the alkalies in portland cement

(b) FELSITE. — Light-colored, fine-grained igneous rocks are collectivelyknown as felsite. The felsite group includes rhyolite, dacite, fine-grainedandesite, and trachyte which are the equivalents of granite, quartz diorite,diorite, and syenite, respectively. These rocks are usually light colored butmay be dark red or even black. When they are dark they are more properlyclassed as “trap” (see Gabbro). When they contain natural glass, the glass

186

frequently has such a high silica content that it is reactive with cementalkalies.

(c) BASALT. — Basalt is the fine-grained extrusive equivalent of gabbro.When basalt contains natural glass, the glass is generally lower in silicacontent than that of the lighter-colored extrusive rocks and is hence lesslikely to be reactive with cement alkalies.DESCRIPTIONS OF SEDIMENTARY ROCKS AND THEIRMETAMORPHIC EQUIVALENTS

13. Sedimentary rocks are stratified rocks laid down for the most partunder water, although wind action occasionally is important. They may becomposed of particles of pre-existing rocks derived by mechanical agenciesor they may be of chemical or organic origin.Carbonate Rocks

14. Carbonate rocks are generally referred to as limestones unless morethan 50% of the carbonate constituent is known to consist of the mineraldolomite, in which case they are called dolomites. If 50% to 90% of thecarbonate content is the mineral calcite, the rock may be called dolomitelimestone; if 50% to 90% is the mineral dolomite, the rock may be calledcalcitic dolomite. Most carbonate rocks contain some noncarbonateimpurities such as silica minerals, clay, organic matter, or hydrous calciumsulfate (gypsum). Carbonate rocks containing 10% to 50% sand arearenaceous (or sandy) limestones (or dolomites); those containing 10%to 50% clay are argillaceous (or clayey or shaly) limestones (or dolomites).Marl is a clayey limestone which is fine-grained and commonly soft. Verysoft carbonate rocks are known as chalk or “lime rock.” Limestonerecrystallized by metamorphism is known as marble. NOTE. - “Magnesiumlimestone” is sometimes applied to dolomitic limestones and calciticdolomites but it is ambiguous and its use should be avoided. The term“lime rock” also is not recommended.Conglomerates, Sandstones, and Quartzites

15. (a) These rocks consist of particles of sand or gravel, or both,cemented together. If the particles include a considerable proportion ofgravel, the rock is a conglomerate. If the particles are in the sand sizes, therock is a sandstone or a quartzite. If the rock, when fractured, breaks aroundthe sand grains, it is a sandstone; if the grains and the cement are largelyquartz and the fracture passes through the grains, it is a quartzite.Conglomerates and sandstones are sedimentary rocks. Quartzites maybe sedimentary or may be metamorphosed sandstones. The cementingmaterial of sandstone may be quartz, opal, calcite, dolomite, clay, iron oxides,or other materials. If the nature of the cementing material is known, thedesignation of the rock may include a reference thereto, as “opal-bondedsandstone,” or “ferruginous conglomerate.”

(b) Graywacke is sandstone containing abundant dark particles of rocks,such as chert, slate, phyllite, and schists, in addition to mineral grains anda matrix resembling shale or slate.

(c) Arkose is coarse-grained sandstone containing conspicuousamounts of feldspar and is derived from granite.

Argillaceous Rocks16. These rocks are largely composed of, or derived from, sedimentary

silts and clays. When relatively soft and massive they are known as clay-stones, or siltstones, depending on the particles of which they arecomposed. When harder and platy they are known as shales, and whenmetamorphosed they become, with progressively greater alteration, slates,phyllites, and schists. All of these metamorphic rocks are usuallycharacterized by a laminated structure and a tendency to break into thinparticles.Chert

17. Chert is a very fine-grained siliceous rock which is characterized byhardness (scratches glass, is not scratched by a knife blade), conchoidal(shell-like) fracture in dense varieties, the fracture becoming splintery inporous varieties, and a variety of colors. The dense varieties are very toughand are usually gray to black, or white to brown, less frequently green, red,or blue, and have a waxy to greasy luster. The porous varieties are usuallylighter in color, most frequently being white or stained yellowish, brownish,or reddish, and have a chalky surface. Dense red and, in some cases,dense yellow, brown, or green chert is sometimes called “jasper.” Denseblack and, in some cases, dense gray, chert is sometimes called “flint.”Chert is composed of silica in the form of chalcedony, cryptocrystallinequartz, or opal, or combinations of any of these three. The determinationof which form or forms of silica are present requires careful determinationof optical properties, absolute specific gravity, or both. Chert occurs mostfrequently as nodules or bands in limestones and as particles in sandsand gravels derived from such rocks.DESCRIPTIONS OF METAMORPHIC ROCKS

18. Since the typical metamorphic equivalents of sedimentary rockshave been mentioned under Sedimentary Rocks, the descriptions belowcover metamorphosed igneous rocks:Serpentine

19. Serpentine is a relatively soft, light to dark green to almost blackrock formed usually from silica-poor igneous rocks such as pyroxenitesand peridotites. It may contain some of the original pyroxene or olivine butis largely composed of softer hydrous minerals. Very soft talc-like materialis often present in serpentine.Gneiss

20. Gneiss is usually formed by the metamorphism of schists or igneousrocks. It is characterized by a layered structure resulting from approximatelyparallel lenses and bands of platy minerals, usually micas, and of granularminerals, usually quartz and feldspars. Gneisses are usually coarser grainedthan schists and usually contain an abundance of feldspar. All intermediatevarieties between gneiss and schist and between gneiss and granite arefound, often in the same areas in which well-defined gneisses occur.

TESTS USED TO DETERMINE PHYSICALPROPERTIES OF ROCK

Compressive Strength (ASTM C170)

1. Sample — cylinder of rock 2" high and 2" diameter

2. Cylinder of rock is placed between a special bearing blockand the head of a suitable universal testing machine.

3. Unit crushing strength is calculated in lbs. per inch2.

Specific Gravity Test(ASTM C127, C128)

1. Size of sample — 5 kg. of plus 3/8" agregate.

2. Wash to remove dust — then dry at 110° C.

3. Immerse in 15° to 25° C water for 24 hrs. and then weigh (B).

4. Determine weight of sample in water (C).

5. Dry again @ 110° C and weigh (A).

6. Bulk specific gravity

7. Apparent specific gravity

Absorption Test

1, 2, 3, 4, 5 and 6. Same as above.

7. Absorption, per cent (%)

IMPACT CRUSHABILITY TEST PROCEDURE

1. Ten to fifteen samples of approximaty 3" x 2" dimensions withtwo natural parallel sides of 2" to 3" widths are selected.

2. Each sample piece is placed on a pedestal and strucksimultaneously by two opposing hammers of standard sizeand shape.

3. The height of the hammers are increased until the sample isbroken and the total foot-pounds (A) of force are recorded.The width (W) of the sample at the fracture is recorded.

4. The work index (W.I.) is calculated from the equation:

5. Two Work Indexes are recorded; The maximum W.I. and theaverage W.I. of the samples tested.

Los Angeles Abrasion Testby Los Angeles Machine (ASTM C131)

1. Size of sample — 5000 grams of clean, dry aggregate, properlygraded (A).

2. Sample placed in machine which is then rotated for 500revolutions @ 30 to 33 RPM.

3. Aggregate then removed and screened on a No. 12 sieve. Materialretained on screen then washed, dried and weighed (B).

4. Percentage of wear

The lower the Los Angeles rating, the harder the rock.

Deval Abrasion Test

1. Sample — about 50 pieces broken by hand from a large pieceof rock — wt. 5000 grams.

2. Sample placed in large cylinder mounted at an angle of 30°with the axis of rotation so that the rock charge is thrown fromend to end twice during each of 10,000 revolutions.

3. Charge then screened over No. 12 sieve and the amountpassing is expressed as a percentage of the initial weight andis called the percent of wear.

4. French coefficient of wear

Dorry Hardness Test

1. Sample — a cylindrical rock core 25 mm in dia. from the rockspeciman.

2. Sample is subjected to the abrasive action of quartz sand fedupon a revolving steel disk.

3. The end of the sample is worn away in inverse ratio to itshardness. The amount of loss is expressed in the form of acoefficient as follows:

Coefficient of hardness

W = loss of wt. after 1000 RPM of disk.

AMPERE RATING OF AC AND DC MOTORSThe full load ampere rating of motors of a given horsepower rating will varysomewhat depending largely upon the type of motor. The full load valueslisted in the following table can be considered “average values” for thedifferent types and makes of motors. High torque squirrel cage motors willhave a full load current at least 10% higher than the full load values listedin the tables. For 25 cycle motors, the full load current value will beapproximately that of a 60 cycle motor having the same number of poles.In other words for a 750 RPM, 25 cycle motor, use the data for thecorresponding 1800 RPM, 60 cycle motor. This rule is reasonably correctfor 25 cycle motors above 500 RPM.
