Sprocket crusher

摘要

A crusher adapted to process a feedstock. The crusher includes a pair of crusher rolls for processing a feedstock, the crusher rolls being disposed in a spaced apart relationship with an axis of each crusher roll parallel to one another. Each crusher roll has a plurality of toothed sprockets spaced along the axis of the crusher roll by a spacer disposed between adjacent sprockets. The sprockets of one crusher roll are interleaved with the sprockets of the other crusher roll such that the sprockets of one crusher roll are aligned with the spacers of the other crusher roll. A lateral displacement device is operably coupled to the pair of crusher rolls and is shiftable between a first position wherein the sprockets and spacers of the pair of crusher rolls are interleaved and a second disengaged position wherein the sprockets and spacers of the pair of crusher rolls are disengaged. The lateral displacement device has a biasing member acting to urge the pair of crusher rolls into the interleaved position.
