Single Roll Crushers McLanahan

The Single Roll Crusher, with its 6:1 ratio of reduction, is ideal for reducing large feed lumps to a medium product size while producing a considerably lower percentage of fines. The minimum product sizing of a Single Roll Crusher is generally limited to 2-3”. The crushing is carried out between the full width of the extra-long curved crushing plate and the low-speed crushing roll. The
