Tra ditional hammer mills work on the principle that most materials will crush, shatter, or pulverize upon impact. Material is fed into the mill's chamber through the feed chute, and struck by ganged hammers, which are attached to a shaft that rotates at high speed inside the mill's grinding chamber.

Hammer mill is the most widely used grinding mill and among the oldest. Hammer mills consist of a series of hammers (usually four or more) hinged on a central shaft and enclosed within a rigid metal case. It produces size reduction by impact.

Wi = Work Index F80 = 80 percent passing size of the feed (micrometers) P80 = 80 percent passing size of the product (micrometers) The Work Index for rod and ball mills can be determined from laboratory tests and, as demonstrated by Rowland, the relationship gives us a reasonably accurate tool for the design of rotary grinding mill circuits.

FEECO hammer mills use a central rotating shaft, with several 'hammers' attached to the pivots on the shaft. When the shaft turns, the hammers are swung via rotational energy, which causes them to collide with the material and break it into smaller particles. Hammer mills are relatively flexible units, used in a variety of applications.
