Roll Crusher - an overview | ScienceDirect Topics

Roll crusher operation is fairly straightforward: ... It should also be noted that the value of the coefficient of friction decreases with speed, so that the speed of the rolls depends on the angle of nip, and the type of material being crushed. The larger the angle of nip (i.e., the coarser the feed), the slower the peripheral speed needs to ...
