Traversing roll breaker apparatus

A traversing breaker roll crushing apparatus for reducing lumps of material on a grid disposed over a material-receiving area, the apparatus comprising:

• (a) a generally U-shaped carriage means including a pair of carriage sections interconnected by an upper frame,
• (b) a pair of track means guiding each of the carriage sections across the grid,
• (c) roll means including shaft means having opposed ends interconnected by motor housing means and operatively mounted in non-rotatable relation to the carriage sections and an outer cylindrical casing mounted in rotatable relation to the shaft means,
• (d) drive means for the roll means including motor means and reducer means carried by the housing means for rotating a ring gear fixedly attached to the outer casing relative to the housing means, and means reversing the direction of the roll means,
• (e) striker means circumferentially arranged on the roll means in spaced relation to the grid for reducing lumps of material as the roll rotates and the carriage means moves across the grid, the striker means including a plurality of rings fixedly attached to the outer casing of the roll means in spaced relation lengthwise of the roll means, each ring including a plurality of sets of circumferentially disposed fixedly operating, removable pick elements each set including pick elements point in opposite directions, and
• (f) drive means for moving the carriage means in opposite directions across the grid so that crushing can be performed by the oppositely pointing pick elements as the apparatus moves in either direction across the grid.
