The breaker plate of a coal crusher has holes therein so that coal small enough to pass through those holes does so without being acted upon by the rotor This increases the capacity of the crusher reduces fines and conserves power The plate is oriented such that windage generated by the rotor urges the smaller pieces of coal through the holes.Read More
