Conveyor for selecting and crushing hard coal

摘要

Using a conveyor according to the main patent, the discharge of fine material through the selecting openings is to be substantially increased. This is achieved in that at least in an approximately central region, in the longitudinal direction, of the slot-like selecting openings (3) there are arranged collision devices (6; 8; 9) for position alteration of parts of conveying material transported above the selecting openings by the drivers (13). <IMAGE>
