UTICA, NY — A new hammer mill Model 141 from Munson Machinery reduces friable and fibrous materials into uniform particle sizes ranging from 20 to 300 mesh.
Centrifugal force causes pivoting hammers to stand at 90° 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 (56 kw) motor at 1800 to 4000 RPM, achieving hammer tip speeds of 8,700 to 19,500 ft/min (2,650 to 5,950 m/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° cylinder screen, the MUNSON® unit features an
