Stone Hammer Mill
A hammer mill crushes material that is friable, by impacting it against a rotating hammer (typically traveling between 750 RPM and 1800 RPM). Then the material is forced against a rugged solid plate called a "breaker plate" which further degrades the particle size. Finally, the material is forced over a discharge grate by the hammers, where crushed finer particles drop through the discharge grate and larger particles travel around for another crushing cycle, until they fall through the discharge grid. During the entire time the material is traveling around in the hammermill it is constantly being impacted by the hammers, and the side of the mill casing, causing breakage of the particles. This sequence repeats itself between 750 - 1800 times each minute, until the particle is ground fine enough to fall through the discharge grid.
