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.

The normal speed of plate mills is between 2500 to 3500rpm, but the friction between the plates and overheating reduces the speed of the mill accordingly [18]. The refinement of the flour ground is achieved by increase in pressure asserted on the grain by narrowing the gap between the plates. The mill should not be run idle
