Like other crusher equipment, the cone crusher must be maintained and overhauled periodically in order to ensure its stable operation after being used for a period of time. However, there are many factors affecting the service life of the cone crusher, such as crushing ore strength, crusher equipment load, etc. How can the cone crusher be maintained effectively,
The following precautions are listed in the crushing equipment factory:
1. Before starting, check the lubrication system and the crushing area of the cone, correct the tension of the belt, and fasten all screws.
2. When the wear of the ore retaining ring under the moving cone exceeds 1 / 2 of the ring height, the steel plate shall be repaired and welded.
3. During normal shutdown, the ore feeding shall be stopped first, and the main motor can be stopped only after all the ore in the crusher is removed. Finally, stop the oil pump motor. After shutdown, all parts of the crusher shall be comprehensively inspected, and the problems found shall be handled in time.
4. When the spherical surface of the body is worn more than 4mm, or the contact between the lower end of the conical surface of the body and the lining plate is worn more than 4mm, the body shall be replaced.
5. Start the oil pump motor for 5-10 minutes, check the working condition of the lubrication system, and start the main motor after it works normally.
6. When maintaining the cone crusher motor cone, the contact between the crusher spindle and the cone sleeve is worn more than 3mm or cracks are found, the spindle should be replaced.
7. The ore feeding can be started only after the crusher runs at no load for 1-2 minutes. Since the cycle crusher is full of ore feeding, it is necessary to pay attention to whether the ore feeding is normal, especially for the ore with much mud and high moisture, to prevent the ore from blocking the ore feeding port. During operation, pay attention to check the ore discharge, and it is not allowed to accumulate ore in the space under the sealing device.
8. When the ore dominated by primary lump ore falls down from the blanking and directly hits the ore distribution plate of the conical crusher, the ore distribution plate will wear quickly (it needs to be replaced in about 3 months). If it is not replaced in time, all 8 M30 bolts fixing the ore distribution plate will be broken by the ore, and the ore distribution plate will fall off, resulting in the jamming of the motor cone and fixed cone of the conical crusher, and even burning the motor, Therefore, the production of medium crushing is affected by shutdown. If you want to improve the service life of the ore dividing plate, you must weld the round steel of 16 to make the outer diameter return φ 300 ring, and then the welded ring is overlapped and crossed up and down on the surface of the ore dividing plate of the conical crusher. In production, the space surrounded by the ore dividing plate and the ring is filled with crushed ore, buffering the impact on the ore dividing plate and greatly prolonging the service life of the ore dividing plate.
The above is the use of cone crusher summarized by the crushing equipment factory. No matter how good the equipment is, it will be maintained regularly, which can increase the service life and ensure your economic interests to the greatest extent.
