Six models are available with an approximate capacity of between 25 and 800 Tons Per Hour. Maximum feed size for the small unit is 4” and 12” for the largest. Capacities vary with speed, size of the desired product and weight per cu.ft. of material being reduced. They don’t require screens for final product sizing and have an open discharge that won’t plug.
Stedman cage mills can be operated in reverse, in order to prolong the useful life of their cages and breaker plates. Maintenance and service are easily performed, and downtime is minimal. Removal of the housing permits easy access to the cage, which can be lifted out through the cover opening. Material fed into the hopper drops onto a bed of like material before falling into the cage, preventing undue wear on the hopper and prolonging the life of the unit. The hopper is hinged so that it can be swung open or even lifted off without being unbolted. Holes in the top flange allow a feeder assembly to be bolted onto the hopper.
The material to be reduced is fed into a rapidly spinning cage of heavy alloy-steel bars. The bars strike the material and smash it into particles, hurling the particles against other bars, breaker plates, and other particles. Each impact reduces the material further until it reaches the desired fineness. This fineness is determined by feed material, mill speed, cage design, auxiliary screen use, and test sample runs.
Test your wet and tacky as well as dry materials in Stedman’s testing and toll processing facility with full-scale cage mills, HSI, VSI and hammer mills to predict output capacities and processing data. Support services include system design and 24-hour parts and service.
