The continuous feed vibratory scrap feeder is a piece of aux i l iary equipment to supplement the operation of side well melters; to provide for continuous addition of scrap charge material. This provides for totally unassisted feeding of scrap material, and usually operates in conjunction with other auxiliary equipment including the GPX vortex submerging device and the automatic salt flux addition
system.

Vibratory Scrap Feeder The attached general layout drawing of this equipment shows the charging box, discharge apron, isolation springs, vibrator assembly, and structural supports. This equipment is furnished with control panel, quick disconnect plugs, and all related equipment to render a completely
functional unit. The principal driving force for the feeder is an infinitely variable force counterweighted assembly. This force is amplified by steel coil springs to
produce a stroke on the feeder trough. The charge container is isolated from the undercarriage supports with a package of six coil
isolation springs. The vibrating bin is also furnished with a locking system that secures the bin to the furnace being
charged. The support structure can be furnished for one of
three positioning modes. These are rail mounted,
freewheeling, or fork truck mounted. The following connections would have to be made
upon receipt of the equipment: 1. 480 volt power to the start/stop station. 2. Attachment to the furnace. This unit has proven to be very popular with a number of our aluminum customers. There are two of these units that have been in operation for almost ten years at IMCO, Inc. in Post Falls, Idaho. One unit has operated for eight years at Commonwealth Aluminum in Lewisport, Kentucky. Two units have been operating for almost seven years at Bens Run Recycling in Bens
Run, West Virginia.
TECHNICAL SUMMARY
Consistent Feeding Variations in head load and material damping cause fluctuations in the capacity and feed rate of scrap feeders that are not sub-resonant tuned. Scrap feeders have negligible change in trough stroke when subjected to varying head load and material damping. Our precision sub-resonant tuned Scrap Feeders maintain stroke consistency and speed stability thus delivering higher capacities at controlled feed rates, and repeatability.
Our Vibratory Scrap Feeders are sub-resonant tuned, two-mass and spring-connected systems.
The Vibratory Scrap Feeder is designed to be an integral part of the Gillespie + Powers, Inc. total plant material han-dling and melting operations. From shredding, to metal out the door, Gillespie + Powers, Inc. offers all aspects for the
efficient aluminum melting process.

Optimum utilization of materials for reduced
waste.
The Gillespie + Powers’ automatic salt/flux feed system includes continuous proportioning and addition of salt fluxes to continuously add material in proportion to raw material charge. This intimate and properly proportioned mixing of salt fluxes with charged material provides for optimum utilization of these materials, reducing
waste and increasing melt recovery.

Salt Hopper
Salt Conveyor
DESIGN FEATURES:
The trough will be formed and fabricated from 3/8” thick AISI C1020 mild steel to provide a bottom width of 60”
with 36” high side x 17’-6” long (including stainless steel section). Maximum charge weight 12,000 pounds. Replaceable 2’-6” long bolt-on stainless steel discharge section bolted to the primary trough will be provided.
The drive is a variable force drive mechanism utilizing the principle of sub-resonant magnification of small exciting force acting upon a two-mass natural frequency coil spring system. The first mass, consisting of the motor and exciter frame, is separated by precision engineered steel coil springs from the second mass, which is the material carrying deck assembly. The small force needed to excite the system is efficiently produced by counterweighted wheels mounted on a totally enclosed vibration design motor with double extended shafts. Centrifugal force pro-duces the desired motion which is amplified by the coil springs and transmitted directly to the deck assembly,
resulting in highly efficient straight-line feed of material. 8” I-Beam frame with heavy-duty casters to support vibrating hopper, Frame is designed to Includes a support
structure necessary to achieve a product discharge height of 60”. The drive unit consist of, heavy-duty coil reactor springs and a VFD ready 15 HP 720 RPM T.E.N.V. vibratory motor, wound for 230/460 volt, 3 phase, 60 cycle power supply, mounted below the trough. The motor is con-
trolled with our integral control for adjustable rate control,. Four heavy duty compression type steel coil isolation spring assemblies, complete with base plates, will be fur-
nished to minimize transmission of vibration to the supporting structure. An independent NEMA 12 control cabinet will contain Honeywell UDC-330 controller, Variable Frequency Drives (VFD), and adjustable ratio relay. A shielded thermocouple is furnished for remote mounting in the furnace for
interconnection with the UDC-330 controller. The unit will be completely assembled and mechanically tested prior to shipping. All exterior surfaces will be mechanically cleaned, power washed, and coated with an industrial production enam-
el. UTILITIES REQUIRED: 230/460V 60amp Power for 15 HP Drive Unit MCC and Remote Switch by Others.

The Vibratory Scrap Feeder is designed to provide a feed rates up to 25,000 pounds per hour of a variety of shredded scrap aluminum into the melting furnace. The feeder will include a support stand on wheels as well as lugs to move with a fork truck. The material carrying deck assembly will have a replaceable stainless steel nose assembly that extends into the furnace well. Each feeder will be equipped with a control box that will contain the
components of the automatic variable feed control system. (Custom controls systems are available at additional cost.)
Vibratory Scrap Feeder TECHNICAL DESCRIPTION
OPTIONAL AUXILIARY EQUIPMENT: • Automatic Salt Feed Mechanism
• GPX Vortex Submerging Device
• GPX Side Well Furnace
• GPX Delacquering System
The Automatic Salt Feed Mechanism is designed to be used in conjunction with the Gillespie + Powers’ Vi-bratory Scrap Feeder, and provide a variable feed rate of salt fluxes based on the material feed rate of
the GPX vibratory scrap feeder.
DESIGN FEATURES:
The automatic salt feed mechanism includes: • Salt Auger Screw Feeder with 6” SS screw with Tivar Liner – 2HP variable speed drive.
• Hopper bolted on top of salt auger screw feeder. Total Nominal Capacity 73 cubic feet.
• Belt wall conveyor 12” OAW with 10” diameter drive and take-up pulley. 2HP variable speed
drive. 18” top angel take-u, 100 FPM nominal.
• Automatic metering assembly Supporting steel stands, hopper side viewing window and variable feed rate control panel, are also included. Suffi-
cient guarding will be provided to shield components installed on base. A completely wired operation control panel is included and mounted on the assembly. This panel includes the on/off switches, motor start, VFD’s, assorted running lights for the equipment, and Motor Over load protection
with alarm. The operating motors include the following: a.) Conveyor - 2 HP, 480 Volt b.) Auger - 2 HP, 480 Volt c.) Discharge Vibrator - Fractional HP, 110 Volt (optional) d.) Control Motor - Fractional HP, 110 Volt (optional)
Also included in the panel will be the Auto-Manual potentiometer station for controlling the range of operation on the discharge conveyor and the auto/manual feed rate controller. The feed rate controller will be set up to receive a 4-20ma signal that may be fed to it from either the temperature of the metal or a signal from a weigh belt convey-or. This allows the continuous automatic adjustment of salt feed in response to changing charge rates. In addition,
this controller can be operated on a manual feed basis.
The unit will be completely assembled and mechanically tested prior to shipping. All exterior surfaces will be mechanically cleaned, power washed, and coated with an industrial production
enamel. UTILITIES REQUIRED: (2) 230/460V 5amp Power for 2 HP Drive Unit(s) MCC and Remote Switch by Others.
