Hammer Mill Model 141

The Hammer Mill Model 141 reduces friable and fibrous materials into uniform particle sizes ranging from 20 to 300 mesh. Centrifugal force causes pivoting hammers to stand at 90-deg to the rotating shaft, throwing material against breaker plate ridges in the feed section, and then against perforated bed screens through which sized material exits. The shaft, integral hammer discs, disc pins and hammers are driven by a 75-hp motor at 1,800–4,000 rev/min, achieving hammer tip speeds of 8,700–19,500 ft/min even under heavy loads, reducing a broad variety of solid material into particles at high rates. The mill can pulverize wood scraps, process grain, break-down impact resistant housings, destroy ammunition shells, pulverize newspaper, separate rubber from cord fiber, and reduce the size of a variety of other chemical, plastic, rubber and agricultural products. Particle size is determined by the size of the screen perforations. In addition to a lower 180-deg cylinder screen, the unit features an extra 90-deg screen located in the hinged section of top case, increasing screen area by 50% to a total of 270-deg, utilizing the entire area of the case.
