The causes of sudden shutdown of cone crusher may involve multiple aspects. The following are some common causes:

1. Electrical and voltage problems

Unstable or too low voltage: When the voltage at the construction site is unstable or too low, it is easy to force the cone crusher to suddenly shut down for self-protection. Therefore, after starting the machine, the operator should check whether the voltage is normal to ensure that the voltage is stable.

2. Feeding and discharging problems

1. Excessive or uneven feeding: During the production process of cone crusher, excessive or uneven feeding will cause the discharge port to be blocked, causing the cone crusher to be overloaded, the fuse to break or the fuse to melt, resulting in shutdown.

Solution: After starting the machine, check whether the discharge port of the cone crusher is blocked by residue. If so, it should be cleaned immediately, and pay attention to controlling the uniform feeding, not too much or too little.

3. Mechanical and transmission problems

1. Belt slippage: The cone crusher relies on the belt to transmit power. If the belt in the drive groove is too loose, it will cause the belt to slip and fail to provide enough power for the normal operation of the machine, causing the cone crusher to stop suddenly.

Solution: Check whether the belt is tight enough and adjust it properly to prevent it from being too tight or too loose.

2. The eccentric bearing sleeve is loose or falls off: When the eccentric shaft fixing sleeve is loose or falls off, there will be no gap on both sides of the frame bearing seat, and the eccentric shaft will be stuck and unable to rotate normally, which will cause the cone crusher to stop suddenly.

Solution: Pay attention to the position of the eccentric bearing sleeve to prevent it from getting stuck, and check and tighten related parts regularly.

3. Bearing damage: The bearing is a very important component in the cone crusher, which is used to reduce the friction coefficient during the working process. If the bearing is damaged, other crushing parts will not work properly, causing the cone crusher to stop suddenly.

Solution: Pay attention to daily maintenance, lubricate and inspect the bearings, and replace them in time if they are damaged.

4. Lubrication and cooling problems

1. Lubricating oil problem: If the lubricating oil in the oil tank is too dirty, used for too long or the oil quality is unqualified, the lubrication quality will be reduced, affecting the normal operation of the crusher. In severe cases, the oil temperature will be too high, causing shutdown.

Solution: Regularly replace the lubricating oil and lubricating oil filter, clean the oil tank, and ensure that the lubricating oil quality meets the requirements.

2. Insufficient cooling: In summer or high temperature environment, if the cooling intensity is insufficient, the crusher will overheat and shut down.

Solution: Strengthen the maintenance of the cooling system to ensure good cooling effect. If necessary, additional cooling equipment can be installed.
