2-3 Typical Features and Components
Infeed
The auger and trough assembly is constructed with the throat opening and an independently
chain-driven auger for the transfer from process machine to the cutting chamber of irregular
shapes of plastic material. A removable trough cleanout cover is provided to fully expose the
auger for maintenance purposes.
Cutting Chamber
The cutting chamber consists of a belt-driven three-blade rotor and two adjustable bed knives.
A lockable, hinged viewport allows viewing of the introduction of material to the cutting
chamber from the auger, the clearing of obstructions, or for other maintenance purposes.
The final granulate size is determined by the hole size of the screen selected. This screen, an
interchangeable feature of the screen drawer assembly, is located between the cutting
chamber and the discharge chute.
Drive System
The drive units consist of an electric motor with drive belts for the cutting chamber, an
electric motor and gear reducer with drive chain for the auger feed, and safety interlocks.
Unless otherwise specified, the motors are provided with separate controls wired for a
common power supply.
Discharge System
A removable discharge chute, located beneath the base, is designed with a take-off tube or
connection to a customer-provided, continuous-running unloading system. A pneumatic
evacuation system is also available.
Base
The base is caster-mounted, with four swivel casters (two locking casters) for easy
positioning.
