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.

Double roll crusher (also called twin roll crusher) is composed of two cylindrical rollers as the main working mechanism (Figure 1). When working, the two round rollers rotate in opposite directions, and the material (ore) is crushed by the friction between the rollers, which rolls the material into the crushing cavity formed by the two …
