Hammer mills utilize steel hammers rotating in a chamber with a section of wall composed of interchangeable perforated screen. Materials cannot exit until particle size is small enough to fit through the holes of the screen.
MUNSON's HammerHead™ Hammer Mills reduce a broad range of friable, non-friable and fibrous materials into particle sizes from one inch (25.4 mm) down to 200 mesh, determined by friability of the material.
