APPARATUS FOR ADJUSTING GAP OF IMPACT CRUSHER

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for adjusting a gap of an impact crusher in which the gap between a hitting plate and a repulsing plate can easily be adjusted optionally and the size of the gap can surely be kept by a simple structure. SOLUTION: A to-and-fro part 65 of this apparatus 60 is made to be a screw type consisting of a bolt member 67 and a nut member 66 to be rotationally driven with a hydraulic motor 64. As a result, the repulsing plate fit to the member 67 side can be moved continuously only by rotating the member 66 by a necessary amount in the normal or reverse direction so that the gap between the hitting plate and the repulsing plate can easily be adjusted optionally. Since the members 66 and 67 are screwed on each other, the gap can surely be kept as it is without shifting in the moving direction of the repulsing plate.
