A Hammer Mill is a machine whose sole purpose is to crush and aggregate materials into smaller particles. It does so by subjecting the material into a series of repeated blows. Hammer Mill grinder is the most broadly utilized in grinding mills for pharmaceutical and chemical and food processing.
Hammers or Knives to grind or crush by impacting materials at high speeds. Rotations per minute (rpm) typically vary from 1,800 to 3,600 rpm. Many designs allow the hammers or knives to rotate clockwise or counterclockwise for more even wear. They come in varying styles or shapes for use in grinding specific materials.
