Abstract. Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute medium-hard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.

A roll crusher is a type of crushing equipment used to reduce the size of materials. Size reduction is accomplished by compressing feed material between two cylindrical rollers that rotate in opposite directions.

The clearance between the roll and the anvil plates can be adjusted to set the maximum particle size at the crusher outlet. Compact & rugged design The core of Magaldi Crusher is a single-roll cam, whose design produces more crushing force than a double-roll design while reducing initial cost and power consumption.
