SELECTION GUIDE

VIBRATION SYSTEMS AND METHODS

The systems that use the vibration technique can be divided into the following categories:

• freely oscillating systems,which will be described in this guide

• oscillating systems bound to resonance,which require specific in-depth research.Please contact the Technical Sales Service of Italvibras

if these systems are required.

The free oscillation system includes two different methods:

• rotational:the vibrating force is directed in all directions through 360 ° in a rotational way,either clockwise or anticlockwise.

• unidirectional:the vibrating force is directed in one single direction in fade-free sinoidal reciprocating mode.

The “rotational ” method is obtained by using a single electric vibrator.

The “unidirectional ” method is obtained by using two electric vibrators with the same electro--mechanical characteristics,each turning in the

opposite direction to the other.

Vibrating force directed in all directions through 360°, in rotational mode

Rotational method Unidirectional method

Vibrating force in a single direction, in sinusoidal reciprocating mode

EXAMPLES OF HOW ELECTRIC VIBRATORS ARE USED IN DIFFERENT PROCESSES

The following examples illustrate a few typical uses:

1 -for conveyors,separators,sieves,sizing machines,unloaders,positioners,sorters,feeders and fluidized beds (“unidirectional method ”(1)).

2 -for silos and hoppers (2A),filters (2B)and vibrating beds (2C)(“rotational method ”).

3 -for compacting tables and tests (accelerated ageing,stress,ecc.)(“Unidirectional (3B)or rotational method (3A)”).

CHOICE OF THE VIBRATION METHOD AND ROTATION SPEED (AND, THUS, THE VIBRATION FREQUENCY) OF THEELECTRIC VIBRATOR APPLIED TO THE ELASTICALLY INSULATED MACHINE, DEPENDING ON THE PROCESS

The choice of the vibration method and vibration frequency able to achieve the utmost efficiency for each type of process,depends on the specific weight

and granulometry (or piece size)of the material used in the process itself (see table. Regardless of the selected vibration method,the electric vibrators

can be mounted on the machine,elastically insulated with its axis in a horizontal or vertical position or,if necessary,in an intermediate position between

the two directrices. The angle of incidence “ i ” (measured in degrees)of the line of force in relation to the horizontal plane should be taken into due

consideration when electric vibrators are applied with the “unidirectional” method. Important the line of force for any angle of incidence must pass

through center of gravity “G” of the elastically insulated machine (see figure next pages).

from 25° to 30° for conveying, unloading, feeding, positioning and sorting;

from 31° to 45° for sifting, grading and separating;

from 45° to 80° for fluidized beds.

Determination of the angle of incidence i of the line of force depends on the type of process and must be within the indicated range.

CHOICE OF THE VIBRATION METHOD AND ROTATION SPEED (AND, THUS, THE VIBRATION FREQUENCY) OF THEELECTRIC VIBRATOR APPLIED TO THE BRUTE FORCE MACHINE, DEPENDING ON THE PROCESS

HOW TO CHOOSE THE RIGHT TYPE OF ELECTRIC VIBRATOR FOR USE IN TYPICAL PROCESSES(e.g.: conveying material)

Use the Table on next page to select the vibration method and the required number of vibrations per minute depending on the process and the

granulometry of the material.

Now move to the diagram corresponding to the obtained number of vibrations per minute: 3000, 3600, ecc.

Choose the corresponding curve on the diagram, for a previously calculated angle of incidence « i » of the line of force.

Using that diagram and that curve: eccentricity value «e» or peak-to-peak amplitude «App», measured in mm and required to obtain the previously

mentioned theoretic product advancement speed value «Vteo

» or «VTEOc

» can be identified for a required theoretic product advancement speed

«Vteo

» (m/h or cm/s) or «VTEOc

» (m/h or cm/s) for tilted machines.

«Vteo

» is determined by the flow of material, taking a reduction coefficient into account (see conveyor channel example below). Given eccentricity

value «e», it is possible to determine the value of the total static moment «Mt» (Kg.mm) of the electric vibrator or vibrators. This value is calculated

by means of the following formula:

Mt = e x Pv

where: Pv = Pc + Po

with

Pv = total weight of the vibrating equipment (Kg);

Pc = weight of the elastically isolated trougth (Kg);

Po = weight of the installed electric vibrator (or vibrators) (Kg); hypothetic weight to be subsequently compared to that of the determined

vibrator.

Important: calculated moment Mt is the total moment of the electric vibrators. For example, if the vibrating machine has two electric vibrators, the

calculated moment must be divided by two to obtain the static moment of each vibrator.

Once the static moment of the vibrator has been calculated, consult the catalogue to determine the type of electric vibrator required.

6

Having chosen the type of electric vibrator, centrifugal force value «Fc» (in Kg) of the vibrator itself can now be found in the catalogue.

Fc

Use formula a = (measured n times g)

Pv

to establish acceleration value «a» along the line of force. This value must be within the range indicated in the Table (on page 8) for the required

type of process.

Attention: if the chosen vibration method is “unidirectional”, value «Fc» to use in the above mentioned formula will obviously be twice the value

indicated in the catalogue as two electric vibrators are installed.

FLOW RATE and SPEED

Vteo

Kr = reduction factor depending on the type of product conveyed

A few values pertaining to this factor are indicated below

Gravel................................................... 0.95 Sand ........................................................ 0.70

Small pieces of coal ............................. 0.80 Sugar ....................................................... 0.85

Large pieces of coal ............................. 0.85 Salt .......................................................... 0.95

Q = flow rate (m3/h)

Vp = speed of product (m/h)

L = channel width (m)

S = layer of material (m)

If free oscillation systems are used, it is advisable to fit anti-vibration mounts (such as helical steel springs, rubber supports or pneumatic

actuators) to allow the vibrating machine to freely move in all directions.

Do not use connecting rods, leaf springs or flat springs, etc., for free oscillation systems.

The non-vibrating element must be of adequate capacity, able to bear a weight equal to total weight «Pt» (i.e. the sum of the weights of the

elastically insulated machine, or the electric vibrator or vibrators «Pv» and the material bearing on the machine itself «Ps») multiplied by the factor

of safety , the value of which is between 2 and 2.5. Capacity «Q» of the elastic element will therefore be:

Now determine the camber «f.»of the elastic system by means of diagram A,

depending on the vibration frequency (rpm of the electric vibrator) and considering

a resonance ratio «r.» (between the vibration frequency of the vibrating complex

and the frequency of the elastic system itself) between 3 and 5. The elastic constant

of the anti-vibrating mount thus equals:

DIAGRAM B gives the percentage of

elastic insulation ( I% ) between the

vibrating structure and bearing

structure, depending on ratio « r ».

The anti-vibration mounts must be

positioned so that the flexure is the

same on all the elements, in order to

balance the machine.

Important: the bearing structure to

which the anti-vibration mounts of the

vibrating complex are fastened must

be rigidly anchored to the ground or to

some other type of bearing structure

and always without any further anti-

vibration elements.

DIAGRAM B

The capacity «Qkg.

» and the elastic

constant «Kkg

.mm

» are the two entities

required to choose the anti-vibration

mounts on the market.

It is absolutely essential to distribute the

load of the vibrating complex evenly over

the elastic system.
