McLanahan | Sampling Sizers/Roll Crushers
Sizer rolls are directly driven by right-angle gearmotor units. This arrangement allows for differential rolls speeds that aid in processing wet and sticky material, but it also simplifies the design of the machine and allows for the minimal footprint associated with sizers. Sample Double Roll Crusher rolls are driven in one of two ways.
Dynamics in double roll crushers
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 Machine Design [el9v7p65o1qy]
A single roll crusher has a roll assembly consisting of a roll shaft and a fabricated roll shell with integral fixed teeth. In the single roll crusher, three different methods of reduction occur: impact, shear and compression. Entering the crusher through the feed hopper, the feed material is struck by the teeth of the revolving roll.
Factors to Consider When Selecting the Proper Roll Crusher …
If the material is hard, shock loading may occur and therefore special consideration needs to be given to the crusher design and drive configuration. ... rule of thumb for single-stage crushers is that a Single Roll Crusher provides up to a 6:1 ratio of reduction and a Double Roll Crusher provides up to a 4:1 ratio of reduction.
