Abstract
A materials processing system adapted for the reduction of metallic materials including a material feed portion configured to convey materials to a mill portion comprising a motor driven rotor in close running fit with a cage mounted grate through which reduced material is discharged onto a conveyer. The cage is biased to a closed operating position by one or more hydraulic rams. A control system receives signals from a speed sensor operatively coupled to the rotor, and is configured to regulate the hydraulic rams, thereby controlling the opening and closing of the cage in response to rotation of the rotor. The control system is further configured to regulate the operation of the materials feed portion to suspend material feed during opening of the cage, permitting trapped or jammed material to be expelled from the mill portion.
