mills have intrinsic cooling due to compressed air expan-sion in the body of the mill. With the help of sweeping air, hammer mills may also be able to process materials with low melting points for coarse grinding applications. Explosibility. The risk of dust explosions must be taken into account when a material is ground very fine in a milling

The amount of open area in a hammer mill screen determines the particle size and grinding efficiency. The screen must be designed to maintain its integrity and provide the greatest amount of open area. Screen openings (holes) that are aligned in a 60-degree staggered pattern optimise open area while maintaining screen strength.
