Abstract: A device for breaking coal and for separating predetermined size coal particles and impurities therefrom. A supply of coal containing rock, shale and other impurities is dumped in a hopper through a top opening. A zigzag-shaped passageway extends from the top to the bottom of the hopper and has a single double action accelerator rotor or a pair of accelerator rotors mounted therein. The rotors increase the speed of the deposited materials that are moving by gravity through the passageway by striking the material and propelling it in the same direction that it was moving prior to being struck. The coal is split upon impact against splitting grates. Chutes located beneath the splitting grates receive the coal particles which pass through sized openings formed in the grates and deposit it in a collection area. The rotors each include a shaft with a plurality of radially outwardly extending blades.

Abstract: A bulk material handling and reclaiming device of a nature that can be added to or substituted in known reclaiming installations. Bulk material such as coal delivered by a conveyor from a mine normally is delivered by a conveyor in large quantities during the period of mine operation to storage areas where it is stacked in mounds covering circular or rectangular storage areas. The new reclaimer has a cage on which a plurality of sets of buckets are moved in either direction by chains to which the buckets are pivoted, the chains endlessly surrounding the cage. The chains are driven to move in either direction in channel tracks. The cage is nonrotatably supported and bodily moved in straight or arcuate paths in either direction toward one or another end of stacked bulk material in storage areas.
