Cone crusher adjusting ring loosening problem caused by parts wear and tear
In the process of cone crusher crushing ore processing operations, the adjustment device is mainly responsible for adjusting the size of the discharge port to control the particle size of the material, which mainly includes the support sleeve, adjusting cap, adjusting ring and locking cylinder, etc., in which the adjusting ring is connected with the fixed cone, the host frame fixing pins and so on, it is one of the most important components in the cone crusher, and it plays a great role for the normal operation of the equipment, and if the adjusting ring appears to be loosened or damaged, then it will cause the production to stop. If the adjusting ring is loose or damaged, then it will cause the production to stop, so it is necessary to know the reasons for the loosening of the adjusting ring of the cone crusher and the solution. Shenyang Shanyou Heavy Industry will talk about the loosening of the adjusting ring of cone crusher caused by the wear and tear of parts.
The adjusting ring is a moving cone with serrated threads on its external cone crusher surface. When the cone crusher is running for a long time, and the threads of the support sleeve and adjusting sleeve show serious wear, it will cause improper clearance between the locking sleeve and adjusting sleeve, thus causing the adjusting ring to loosen. In addition, the locking bolt of the cone crusher plays the role of fixing the equipment, when the locking bolt is worn out, it will also cause the adjustment ring to jump.
Measures: When the threads of the support sleeve and adjustment sleeve are worn, the threads should be repaired or replaced in time. In addition, the gap between the locking sleeve and the adjustment sleeve of the newly installed cone crusher is generally 12.5mm, and the gap can be enlarged appropriately according to the wear and tear of the threads of the adjusting and locking rings and the locking stroke can be enlarged to increase the locking stroke, which can reduce the loosening of the adjusting ring as well.
