Get Pricemills 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
Get Price3.2 Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed
