A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding
Hammer Design The design and placement of hammers is determined by operating parameters such as rotor speed, motor horsepower, and open area in the screen. Optimal ham-mer design and placement will provide maximum contact with the feed ingredient. Mills in which the rotor speed is approximately 1,800

Hammer mills use large rotating drums with protruding metal bars (i.e., hammers) that impact the material at high veloc - ity to shatter and tear material particles. Typically, the metal bars swing freely from the drum, but fixed hammers are also common in hammer mill designs. Hammer mills are recognized as technology capable

hammer pin. Excessive wear of the hammer holes or grooving of the pins generally indicated an inconsistent feed (surges that cause the hammers to rock on the pins) or the need for a heavier hammer pattern. This is especially true on machines with lower tip speeds such as 38" diameter mills with 1800 RPM motors. As hammer manufacturers improve the

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.
