Japanese Patent JPS501001
Kind Code:
A
Abstract:
In an apparatus for reducing automobile bodies to scrap suitable for use in metallurgical furnaces, automobile bodies, front end forward are placed on an inclined chute, one behind another, the chute accommodating two bodies in tandem. Power-driven feed rolls, the upper one of which is vertically movable, control the rate of feed of the lead body into a reducing mill having an upright rotor with a shell of downwardly decreasing diameter having a replaceable lining therein. Spaced knocker arms with cutters at the free ends, forming the top of the rotor, progressively shear and rend the lead ends of the car body as it projects into the mill and the pieces are further broken up and rolled into balls and otherwise irregularly shredded and compacted as they then move down between the rotor and the shell lining, the rotor having ring hammers at intervals around its periphery from a level just below said arms to its bottom. The end product drops into an annular trough from which it is expelled by vanes at the bottom of the rotor. Four motors with drive pinions arranged around a central gear wheel on an extension drive shaft at the bottom of the rotor drive the rotor at high speed.
