The DRC-Double roll crusher is designed in such a way that the rollers can be reversed from standstill with extremely high starting torques. Foreign objects that cannot be crushed are automatically released from the crushing chamber. This is done with the help of the hydraulic gap adjustment, which can open and close the crushing gap fast.

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.
