Derivation Of Angle Of Nip In The Roll Crusher

Derivation Of Angle Of Nip In The Roll Crusher The nip angle of the crusher jaw plates will determine the effectiveness of the machine the crushing action takes place low in the jaw cavity and is referred to as the choke point if the nip angle is too big then the jaws will not be able to grab the material and often in this case the material is pushed upwards.

Roll crushers

24 04 2015  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
