### Dual Roll Crushers How They Function

Roll crushers have a theoretical maximum reduction ratio of 4:1. if a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch. roll crushers will only crush material down to a minimum particle size of about 10 mesh (2 mm). a roll crusher crushes using compression, with two rolls.

### Roll Crusher

### Roll Crushers

The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle. it depends on the surface characteristics of the rolls. usually, the nip angle is between 20 and 30 but in some large roll crushers it is up to 40.

### Dual Roll Crushers How They Function

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. some major advantages of roll crushers are they give a very fine.
