Abstract

Breaking apparatus for use with a conveyor and intended to be used in a coal mine comprises a frame generally of inverted U-shape bridging the conveyor and secured to its opposite side walls. A rotary breaking element is drivably carried on an arm assembly mounted on the frame, and a reaction plate on the frame is spaced from an adjacent periphery of the rotary element. In use, coal and rocks on the conveyor pass between the rotary element and reaction plate where they are broken up by the rotary element as it rotates.
