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.
