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.

Roll Crushers are compression-type machines, so output gradation is controlled mainly through the gap setting between the rolls. A wider setting results in a coarser product. A wider setting also provides greater throughput. Single Roll Crushers feature a low-speed crushing roll that crushes material against a curved crushing plate.

The rolls are operating with 5 m/s or more and shear and compression forces crush the material between the roll in the gap. The crushed material is released through the crusher base frame onto a discharge conveyor. The floating roll enables the crusher to release tramp metal and adjust the gap by the hydraulic supported gap setting system.

The crushing rolls can be rotated either inward or outward at slow speed and high torque, which minimizes slippage and fines generation. Slow-speed Sizers are selected for the specific material and lump size to be crushed. Tooth profile selection allows the material to be grabbed and pulled into the crushing zone for maximum efficiency.

6.2.3 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is employed.
