1. Hammer mills: In a hammer mill, swinging hammerheads are attached to a rotor that rotates at high speed inside a hardened casing. The hammer mill consists of a steel casing in which a central shaft is enclosed to which a number of swinging hammers are attached. When the shaft is rotated the hammers swing out to a radial position.
A hammer mill is a rock crusher that employs a rain of hammer blows to shatter and disintegrate a variety of materials. Hammer mills produce a finished product size that is dependent upon the following criteria: Openings in perforated screens or grate bars. Number, size, and type of hammers. Grinding plate setting.
