Cone crusher adjustment reasons set loose

In normal operation the cone crusher, the adjustment may occur sleeve loosening, then what causes the adjustment sleeve loose it? Here we look at the cone crusher adjustment sets loose reasons.

Parts damaged or broken：

1, most of the new cone crusher installed its locking sleeve and gap adjustment sleeve is 12.5mm, according to the adjustment ring and threaded locking ring wear, appropriate to enlarge the gap between the two, increase the locking stroke. And when the cone crusher long-term operation, thread galling may occur serious cases, undue gap locking sleeve and adjustment sleeve, causing loose adjustment sleeve.

2, cone crusher locking ring and the adjustment ring with four M27 bolt junctions, when impurities inside the device enters or feed particle size is too large, so that the cone crusher overload causing the locking bolt fracture, causing the lock failure cause of the adjustment sleeve loose.

3, cone crusher rolling acetabular wall and the wall is too thick will also make adjustments set loose, so when the broken wall wear refrain from welding methods, should replace the broken wall and rolling acetabular wall.

Improper operation
1, cone crusher largest feed particle size of 215mm, if larger than this size of input materials to the crushing cavity, it will cause the device to overload, crushing load increased, the locking force is relatively insufficient, causing loose adjustment sleeve.

2, in the feeding process cone crusher, if uneven feed hopper or crusher to the ore malposition, will lead cone crusher unilateral force is too large, leading to loosening of the adjustment sleeve.
