The Stedman “H” Series™ Multi-Cage Mill is available in 2-4 or 6-row design and in four sizes up to 250 TPH. The design features also include air cannons, heaters and hydraulic ram. The air cannons are mounted at the intake and discharge to help prevent build-up of wet sticky material, while the heaters are also installed on the grinder housing to retard buildup of wet material. The hydraulic ram eliminated the gear head motor and rack & pinion that were used on other Stedman cage mills, now costing less to maintain. The cage mill is a selective crushing, controlled-impact, multi-cage mill designed for sizing minerals and agglomerates, whole grains, chemical, ores and many other materials. Process wet materials as well as dry materials into a carefully controlled uniform particle size.
