Roll Crusher
The nip angle is affected by the distance between the rolls. 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°.

BTMA-What is the principle of a roller crusher?
The particle's angle of nip (the nip) is the angle below which the nip is formed, and above which the particle skids. The radius of each roll is R. The maximum particle size is set by a variable called X. Then, the particle must be of the appropriate thickness to grip a roll. The roll crusher working principle mainly involves choked crushing.

For this reason the nip angle is different for each roller gap. Fig. 32 shows how the nip angle is changing by changing the roller gap. As the roller gap increases the nip angle increases, too. The nip angle changes from 14° to 30° upon an increase in the roller gap from 1 to 2.5 mm respectively. This trend is opposite to pressure change as ...
