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 Simple, Efficient Crusher The elimination of timing gears makes operation of the Double Roll Crusher simple. Dual drive arrangements use a separate electric motor and V-belt drive for each roll, resulting in quiet operation and minimal vibration. For single drive arrangements, power is transferred to opposing rolls by an inter-stage V-belt drive.

The single-roll crusher has a tip speed of 400-450 ft/min while the 6- x 7-ft teethed roll crusher has a normal, no-load, surfaces speed of just under 3500 ft/min. It can be readily appreciated that this high velocity induces an extremely violent crushing action, in conjunction with the 3- to 4-in. knobs which protrude from the roll surfaces.
