Roll Crusher

Roll Crusher

The roll crusher is of simple structure, reliableoperation, and low cost. The particles are drawn into the gap between therolls by their rotating motion and a friction angle formed between the rollsand the particle, called the nip angle. The two rolls force the particlesbetween their rotating surface into the ever smaller gap area, and it fracturesfrom the compressive forces presented by the rotating rolls.

Some major advantages of roll crushers are that they give a very fine productsize distribution and produce very little dust or fines. Rolls crushers areeffectively used in minerals crushing where the ores are not too abrasive andare also used in smaller scale production mining of more abrasive metal ores,such as gold. Currently, coal is probably the largest user of roll crushers.Coal plants will use roll crushers, either single roll or double roll, asprimary crushers, reducing the ROM coal. These crushers will usually have teethor raised forms on the face of the roll. (When used for minerals and metal oresthe roll crushers have smooth faced rolls.)

Applications
Theroll crusher is used in middle and small sized mines for intermediate and finecrushing of the brittle and soft ores of intermediate hardness like coal andcoke.
