course or fine grinding. The output (volume) of the hammer mill is dependent upon the screen size, shaft speed (normally between 1800 to 3,600 rpm), and the configuration of the hammers. The main problem related to hammer mills is the high wearing rate of the structure and the hammers, which are usually made of cast iron.

mentioned that a hammer mill with 16 hammers, a 4.58 mm screen, and an operating speed of 3600 r pm was more effective at grinding a mixture of 1.24 mm
Industrial hammer mills are employed in particle reduction applications for processing material. Though machine designs vary, the basic hammer mill working principle remains the same—uniform size reduction of aggregate raw material is achieved by repeated blows with hammers mounted to a rotating shaft.
