Roll CrushersScienceDirect

 · Rock particles are usually fed through a chute designed to distribute the charge evenly along the width (length) of the roll. About two-thirds of a roll–width is active. As in any crusher particle sizes less than the distance between the rolls tend to pass through uncrushed. Particles that are larger than the opening are nipped and crushed.

 · The capacity of the primary crusher should be chosen to exceed the average capacity of the plant. Since in most quarries the only surge capacity between the quarry and the primary crusher consists of rock being loaded in trucks or cars any operating delays at the quarry will result in a subsequent delay at the primary crusher.
