Operations

Installation of the double shaft crusher is on a platform or on top of a pit. Feeding is done with a vibratory feeder. Material is crushed between two rolls rotating at different speeds. Grinding gap and grinding pressure can be adjusted. Fine material gets discharged to the bottom of the machine housing.

Smooth rolls are standard. A variety of different roll designs is available to be able to adapt to different crushing applications. Bearings are outboard and no grease can enter the grinding chamber. The rolls are each driven by a gear motor. Speed adjustment by frequency control is available as an option, as well as hydraulic motors.
