HAMMER MILL Method of size reduction: Impact Construction and working principle: Hammer mill consists of a stout metal casing, enclosing a central shaft to which four or more hammers are attached. These are mounted with swivel joints, so that the hammers swing out to a radial position when the shaft is rotated. The lower

whereas the hammer tip is travelling at a minimum of 16,000 feet per minute (4,880 m/min) and perhaps in excess of 23,000 feet per minute (7,015 m/min) (high kinetic energy). The transfer of energy that results from this collision fractures the grain into many pieces. Sizing is a function of hammer-tip speed; hammer design and
