 The moving cone of the cone crusher mainly bears the heavy burden of crushing materials. At the same time, due to long-term overload work, the moving cone will also cause a certain amount of wear. Some customers' cone crusher mobile cones wear out very quickly, which requires more attention. , Below are several common situations.

cone crusher

1. The nature of the feed material does not meet the requirements
The hard material broken on site is the main cause of damage to the moving cone. When the material with too large granularity and hardness enters the cone crusher, it will cause serious abrasion on the moving cone. Especially when there is excessive iron in the cone crusher, or other non-crushed objects enter, it will cause serious wear to the moving cone.
2. Overload operation of equipment
Many manufacturers will further reduce the particle size of qualified ore and increase the amount of ore to increase the productivity of the cone crusher, resulting in long-term overload operation, which will further increase the burden on the moving cone, and the loosening of the cone will cause the gear and the moving cone to become loose. Wear.
 3. Poor contact of the supporting surface
During the installation process of the moving cone, special attention should be paid to the dustproof of the working surface such as the eccentric bushing, spherical tile, tapered bushing, and straight bushing of the frame. After installation, use soft lead to measure the clearance and contact area of ​​each mating surface to make it meet the requirements. The moving cone of the cone crusher is supported on the spherical bearing bush of the spherical bearing seat. When the spherical bearing is worn or there is quality problem, the moving cone will move down, and the supporting contact surface will not be in good contact, which will cause the moving cone. The friction has increased, * to severe damage.
4. Unbalanced force on the moving cone
When non-crushed materials enter the body of the cone crusher, uneven ore feed at the feed port or damage to the locking cylinder of the cone crusher, etc., the moving cone will be subjected to impact loads more frequently. Under the long-term action of heavy load and alternating load, the micro-cracks gradually expand, resulting in damage to the moving cone.
