ABSTRACT:
A self-cleaning coal bypass and debris separation grid assembly has a sizing/segregating grid for particulate material such as coal, and a debris bypass grid downstream to bypass the coal to a coal crusher and separate any debris which might damage the crusher. Clearing mechanisms are provided for both the sizing/segregating grid and the debris separating grid. The clearing mechanism for the debris separating grid is preferably a rotating clearing comb having arcuate fingers yieldably mounted to a rotating axle shaft. The arcuate fingers are preferably adjustably tensioned to the axle shaft.
