Track Plant Features

Vibrating Grizzly Feeder - Feeding the materials into the Impact Crusher and/ or
fines chute is a SCE 1200mm x 3975mm long vibrating grizzly feeder including :-

Vibrating Unit - Two individual, out of balance units called exciters are mounted under
the rear of the vibrating feeder. They are driven by a single hydraulic pump and produce a
forward linear motion.

Pan - The feeder floor is fitted with Hardox 400 bolted replaceable wear liners. These
extend the quality and life of the feeder.

Grizzly Section - The grizzly section is a double step grizzly that is easily removed.
Fitted beneath the grizzly is a secondary mesh screening facility for screening a finer product.

Feed Hopper - The feed hopper is the manufactured from Hardox 400. To raise and
lower the wings, hydraulic cylinders are used to bring the travelling height down to a
minimum and allow for maintenance to the vibrating feeder.

Track Frame - The track is manufactured from heavy- duty frame steel having 3.8m
longitudinal centres along with 400 wide tracks as a standard with an overall track width of 2.8m.

Forward Product Conveyor - The forward product conveyor or main conveyor is a
1200mm wide, troughed belt conveyor with a fixed tail section and a discharge height of
3.2m high. The belt is driven via a hydraulic drive motor.

Side Discharge Conveyor - 600mm wide giving a discharge height of
approximately 2.1m. The belt is driven via a hydraulic drive motor. The side discharge dirt
conveyor is hydraulic folding (optional).

Fines Transfer Chute - Fitted beneath the vibrating grizzly is the fines transfer chute.
This chute transfers the material passing the grizzly bar setting onto either the forward
product conveyor or the side discharge conveyor. Material can also be blended if required.

Magnet - A magnetic cross- belt separator is suspended over the on- plant product conveyor
and is complete with permanent magnet and a hydraulic drive (optional).

Powerpack - Caterpillar model C9 engine with electronic governing and emission control
powers the plant. Rated at 350 bHP continuous (265 kW) @ 2000 rpm designed to drive
the impactor via a manually operated heavy- duty twin disc clutch.

Extra Heavy Duty Rotor - SCE - HD Impact Crushers incorporate heavy- duty open
disc style rotors with four blow bars as a standard. Absorbing energy generated by impacting
forces is the key to success in crushing large feed sizes. Providing high inertia ensures
optimum crushing is achieved. The rotor is supported by bearings mounted in suitable solid
housings manufactured from steel blocks with self- purging labyrinth seals.

Hydraulic Impact Arms - Impact plates are identical cast blocks that are inter-
changeable, thereby permitting optimum utilization. Gap settings between impact arm and
rotor are adjusted via hydraulics to allow the product size to be controlled. Hydraulic pressure
on the impact arms is pre- set to resist the passage of uncrushed material through the
impactor. If overloading, power failure, etc. causes material to exceed the pre- set pressure the
impact arms retract in a controlled manner. Following completion of the retraction movement,
the arm returns to its set gap position.

Options - Special features are available depending on the client's requirements. A few
examples; A conveyor weigh scale, extended hopper wings, side conveyor, variable feed
configuration for the crusher for secondary/ tertiary applications.
