The jam of the cone crusher is often because the equipment presents some sudden shortcomings, which seriously affects the production process and reduces the service life of the equipment and components. Let's look at the three major phenomena of the jam of the cone crusher.
 
1.The moving cone and adjustment sleeve are stuck

1. When the cone crusher is running under load, the lock will fail due to the loss of pressure in the hydraulic station, and the adjustment sleeve will rotate with the cone. If the post personnel do not find and deal with it in time, it will cause the adjustment sleeve to jam, and then cause the cone crusher to s*.
2. The jamming of the adjusting sleeve may also be caused by poor thread lubrication, sealing of the adjusting cap or dust cover, abrasion of the adjusting sleeve and support sleeve, or long-term overload operation of the cone crusher. 

2.Material jam and jam

1. The cone crusher feeds too much material or the nature of the material does not meet the requirements, and then forms the cone crusher to block the material, which will cause the crusher to operate excessively, the circuit will be actively protected and the machine will be interrupted, and cone crushing may even occur The machine stuck and forced to shut down.

2. When iron or other unbreakable objects enter the cone crusher's crushing cavity, it will also cause the cone crusher to block materials or even the equipment to jam.

3. the spindle is cracked and stuck

1. Improper use of the cone crusher is one of the main reasons for the main shaft cracking. For example, in order to reach the required discharge fineness, the discharge port is continuously tightened. If unbreakable materials enter the crushing cavity, it will have a clean impact on the main shaft. , The main shaft of the cone crusher is cracked and stuck.   
2. On the other hand, when the cone crusher is in overload operation for a long time, although there is an overload protection device, the damage to the equipment cannot be avoided. The main shaft is prone to cracking and the equipment is stuck.
