Lump crusher for a scraper chain conveyor

摘要

A coarse crusher (18) for use at both face ends of a face conveyor in an underground mine is disclosed. The coarse crusher (18) may comprise a pan module (20), a base-frame module (22) and a support-arm module (24). The pan module (20) has two pan outer longitudinal sides (46, 48). Depending on the face end of the face conveyor, into which face end the coarse crusher (18) is to be integrated, the base-frame module (22) may be fastened releasably via first pan fastening apparatuses (50) to that first or second pan outer longitudinal side (46, 48) which faces away from a working face.
