Abstract

Discloses a mined ore processing apparatus to process mined ores, such as oil sands ore, into granular material. An ore processor bed receives the ore to be processed. The ore processor bed has a frame supporting several rotating elements each separately driven to provide independent rotation rate and direction from the other. The ore processing bed is operable as a sizing device to decimate mined ore supply into granular material and separating it from rocks and other large lump mineral materials found in situ. The ore processing bed may be oriented to provide an upward inclination, which, when combined with alternating rotating element rotation directions, provides a crushing action to the ore material to crush larger rock. Alternately, a rock crusher is also provided to disintegrate oversized materials.
