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 process Dust laden air can give rise to devastating dust explosions Unless the material is one of the few commonly known to present no dust explosion risk a stable
Many particle size distributions can be represented by the Gaudin Schuhmann equation Impact mills use revolving hammers to strike incoming particles and to break or fling them against the machine case Figure 1 The hammers might be fixed or more commonly pivoted Typically the hammers can be reversed to provide added life before they need to be replaced Figure 1 In jet mills
