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.
