Oct 18, 2015 A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the Rolls. 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. 1018201514ch42, 14ch24 4 5.
