· A roll crusher, also known as a double roll crusher, is a type of compression machine used to crush hard materials. It consists of two large metal rolls that rotate in opposite directions. The material is fed into the gap between the rolls and is crushed by the compressive forces exerted by the rotating rolls.

· A toothed double-roll crusher (referred to hereafter as TDRC) consists of a pair of oppositely rotating rolls, which have a series of intermeshing teeth protruding from the roll surfaces. The crushing action of TDRC is a combination of compression and ripping, where the teeth can dig into the rock and larger pieces than the roll diameter can

· 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.

· There are two main types of impact crushers: horizontal shaft impactors (HSI) and vertical shaft impactors (VSI). HSI crushers utilize a horizontal rotor that throws the material on stationary anvils or curtains, which results in the material breaking upon impact. VSI crushers, unlike the traditional crushers, have a vertical rotor which

Roll Crushers. Roll Crushers are compression type crushers, and were once widely used in mining. They have, within the last 10 or so years, fallen into dis-favor among mining and processing companies. The probable reason is because the large mines require very large crushed product output with minimal cost, makes the roll crusher uncompetitive.
