Understanding the Basic Working Principle of Hammer Mills
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.
