The singleroll crusher has a tip speed of 400450 ftmin while the 6 x 7ft teethed roll crusher has a normal, noload, surfaces speed of just under 3500 ftmin. It can be readily appreciated that this high velocity induces an extremely violent crushing action, in conjunction with the 3 to 4in. knobs which protrude from the roll surfaces.

Toothed Double Roll Crushers are used for crushing of friable and brittle materials like Coal, Coke, Sinter hot and cold, Clay, Earth, Slag, Chalk, Soft Limestone etc. Due to cutting action of the teeth, crushing of material takes place mostly due to shear and not by pressing. Therefore fines generation is bare minimum.
