5. 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 …

into the roll crusher is determined by the radius of the roll R roll gap L and the angle of nip From Equation 3 the maximum size of the particle that can be fed into the machine is 2 75mm A hollow cylindrical shaft is used to build the roll Design Fabrication and Testing of a Double Roll Crusher .
Fundamentals of roll crusher grinding. In a roll crusher, material is fed from the top into a narrow gap (called the nip) between rotating cylindrical rolls, which grind the material to the desired particle size. Roll crushers can be configured with one, two or three pairs of rolls, depending on the application.
