ABSTRACT:
At a coal handling facility a reducing machine is mounted on a common carriage along with a by-pass chute, and this carriage is capable of moving either the reducing machine or the by-pass chute into a position directly beneath a receiving hopper. When the by-pass chute is directly below the hopper, coal passes through that chute without interference. However, during winter months when moisture has a tendency to freeze coal together into large lumps, the carriage is moved to bring the reducing machine directly beneath the receiving hopper. The reducing machine has a rotor which engages the large lumps of frozen coal and reduces them to a size more suitable for conveyors and other coal handling equipment. Thus, the coal passes through the reducing machine only when it is necessary to break the frozen coal into smaller lumps, and this in turn prolongs the life of the reducing machine. The carriage has retractable wheels that enable it to rest on a foundation when the reducing machine or by-pass chute are in use. The carriage also has jacks for elevating it so that the wheels may be extended to and retained in an extended position for movement of the carriage along its foundation.
