The feed stream flows between the rolls of the Double Roll Crusher. The rolls of the Sizer rotate at a set speed of approximately 50 rpm (primary and secondary) or approximately 88 rpm (tertiary), which is dictated by the gear reduction of the reducer when powered by an 1800 rpm electric motor. The slower roll speed proves advantageous to ...
In roll crushers, the material is pulled between two counter-rotating rolls which exert a shear force on it. The material breaks and reduces in size due to this force. This kind of crushing works better for materials that have a layered or flat structure because the shear forces can easily split the material along the weak planes.
Compression crushers include jaw crushers, cone crushers, gyratory crushers and roll crushers. Impact crushers include vertical shaft impactors or horizontal shaft impactors. Compression crushers require much less maintenance; high impact crushers undergo more wear and tear due to the material colliding within the crusher.

5. Roll Crushers: Roll crushers are primarily used for secondary or tertiary crushing where fines generation is undesirable due to their low reduction ratios compared to other crushers. Each type of crusher offers distinct advantages depending on factors such as feed size, hardness, desired output size, and budget constraints.
Abstract Four different roll designs were evaluated on a test bench roll crusher/splitter to determine feeding and crushing efficiencies. For each design, different gap settings for the primary and secondary rolls were tested at two hydraulic cylinder pressures on the primary crush roll to determine their ability to crush and/or feed tree bolts.
