Mine Roll Crusher Usage and Application

The Mine Roller Crusher is Mainly used for the crushing of medium or lower-hardness mines and

rocks with medium or lowerrigidity in mine selection, chemicals, cement and building materials

industrial production.

Roll Crusher Working Principle

A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap

between the rolls. The gap between the rolls is set to the size of product desired. The particles are

drawn into the gap between the rolls by their rotating motion and a friction angle formed between the

rolls and the particle, called the nip angle. The two rolls force the particle between their rotating

surface into the ever smaller gap area, and it fractures from the compressive forces presented by the

rotating rolls.

Roll Crushers Main Features and Benefits

Some major advantages of roll crushers are they give a very fine product size distribution and they

produce very little dust or fines. Rolls crushers are effectively used in minerals crushing where the

ores are not too abrasive and they are also used in smaller scale production mining of more

abrasive metal ores, such as gold. Coal is probably the largest user of roll crushers, currently, though.

Coal plants will use roll crushers, either single roll or double roll, as primary crushers, reducing the

ROM coal. Usually, these crushers will have teeth or raised forms on the face of the roll. (Roll

crushers used for minerals and metal ores have smooth faced rolls.)
