The apparatus includes a housing having an inlet for coal and the like and two outlets, a sizing grate, a comb, and means for moving the comb relative to the grate for dislodging granular material clogged therein. The grate is affixed to the housing and provides a plurality of openings which are sized to allow granular material of a predetermined size to pass therethrough to the first outlet, while granular material of a greater size is the second outlet to a crusher. The invention also includes a method of automatically sizing granular material using a self-cleaning grate assembly.
