Impact stone crusher with trough-shaped housing - has aresting wedge displaceable orthogonally in guide groove wall

摘要

The impact crusher bars are set in equidistant, radial grooves round a multi-disc rotor, carried by a motor-powered shaft in the walls of the trough-shaped housing. The leading edges of the bars act as crushing edges, and the bar sides are recessed within the guide grooves to permit stages radial adjustment into positions to be held by an arrester wedge, which positively locks the bars in their grooves. The arrester wedge (17) is displaceable in the wall are of the groove (6) at right angles to the groove lines to lock into one of the recesses (16) in the side of the crusher bar (5). USE/ADVANTAGE - For aggregate preparation for concrete, etc., with impact bar adjustment without its removal.
