Popular Double Roll Crusher Top Quality

 

Application

The Mine Roller Crusher is Mainly used for the crushing of medium or lower-hardness mines androcks with medium or lower rigidity in mine selection, chemicals, cement and building materialsindustrial production

 

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 .

 

Main Features and Benefits

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