Capacity also depends on upon the speed at which the mill is operated, the feed size and its specific gravity, and the size of the desired product. Cage mills work by reducing the material they are fed to predetermined smaller sizes by striking repeatedly with cage pins and throwing the particles at high speed against each other, against the ...
Pulverizer mills act as size reduction equipment. They reduce coarse materials like coal and gypsum at high speeds to tiny granules for a variety of applications. Centrifugal force powers the pulverizers to grind feed materials down to the required size. Pulverizing is typically defined as reducing to 25 mesh and beyond, but Williams machines ...

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.
Sometimes referred to as crushers, hammer mills provide an efficient solution for breaking down oversize granular materials at a high rate of production, without the use of a grinding action. They are particularly robust and adept at processing demanding materials. Particle Size Reduction: Why it's Important
