Failure analysis of HP300 cone crusher
Author:xixi Addtime:2018-07-27 Click:
1, HP300 cone crusher may appear man-made faults
(1) the bushing on the moving cone is seriously worn by the spherical tile, which causes the inner sleeve of the moving cone (usually copper sleeve) to fall off, the copper chip blocks the spherical tile oil passage, and causes the crusher to vibrate when it is running
(2) the fixed cone can not be taken out of rotation with the adjusting ring, which can not be replaced normally. The fixed cone lining plate can not replace the wearing parts in time
2, HP300 cone crusher appeared man-made fault analysis
(1), dynamic cone liner inner wall wear. The moving cone is smoothly arranged in the spherical bearing supported by spherical bearing frame, and is fixed on the eccentric sleeve of the weight (weight and by side cover) close to the operation personnel, due to neglect of check, side cover wall severe wear failed to find the impact crusher counterweight wall directly, and side cover and the counterweight fixing screws loose, fall off, can not directly cause the moving cone balance operation, leading to dynamic cone sleeve are spherical bearing outer surface of serious wear, crusher caused a strong vibration.
(2), fixed cone cannot ring normal rotation and adjustment. Remove the fixed processing cone outer diameter screws, through heavy thread engagement and adjustment ring supported on the adjustment ring, the adjustment ring inside the fixed cone along the clockwise or counterclockwise direction of rotation can be adjusted up and down, to adjust the feeding port and the discharge port size, and for regular replacement, fixed cone liner. In actual operation, the operation time is too long tapered liner normal wear larger HP300 crusher feed cast steel piece of iron iron cannot promptly suck large except on tape machine (such as mining machine bucket teeth etc.) but the operator fails to find directly into the artificial detection.Into the crusher, crushing the iron machine failure protection, can only be forced by the iron crusher extrusion, parts of the fixed plate lining bag convex, causing the fixed cone can not be removed.
