How it Works: Crushers, Grinding Mills and Pulverizers ...

 · Hammer mill Impact mills are similar in construction and principal to HSI and VSI crushers. Impact mills are used to pulverize feed material by impact against a surface or a bed of feed material. The feed material may be propelled by gravity or by a rotating impeller or rotor. The impellers or rotors can be vertically or horizontally orientated.


O''Bryan (1996) reported a negligible gain in throughput for a critical size material less than 5% of the feed of an autogenous mill. Similarly, Mosher, Banini, Supomo and Mular (2006) suggests that pebble crushers, in general, should be designed to accommodate 25-35% of the new SAG feed tonnage.
