Hammer mill is one of the machines used in size reduction. Hammer mills reduce particle size by breaking due to the impact of the hammers, shearing by the edge of the hammers and screen, and collision among the product and in between the product and machine. The impact is the primary force to reduce particle size in a hammer mill.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
