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.)
