Grinding mills and pulverizers are the second level of material reduction equipment after crushers. Mills and pulverizers transform materials through pressure or blades to grind, cut or crush it. As there is with crushers, there are many different types of grinding mills and pulverizers available.

Wet grinding often takes place in ball, pebble or rod mills. The efficiency of wet grinding can be higher than that for dry grinding, but wear of equipment is also higher [2]. Most size-reduction equipment is subject to heavy wear and therefore parts, such as casing liners, hammers and jaws, are designed for relatively easy replacement.

Roller mills accomplish size reduction through a combination of forces and design features. If the rolls rotate at the same speed, compression is the primary force used. If the rolls rotate at different speeds, shearing and compression are the primary forces used. If the rolls are grooved, a tearing or grinding component is introduced.

d1/d2 is known as the size reduction ratio (RR) and is used to evaluate the relative performance of different types of equipment. Coarse grinding has RRs below 8:1, whereas in fine grinding, ratios can exceed 100:1 (Brennan et al., 1990). 2. Rittinger's law states that the energy required for size reduction is proportional to the
