How it Works: Crushers, Grinding Mills and Pulverizers
Jaw crushers use mechanical pressure to break the material by forcing it between two vertical jaws, one stationary and one that is driven back and forth. The gap between the two jaws narrows as the material moves through the crusher, further reducing the size. ... Hammer mill Impact mills are similar in construction and principal to HSI …
