Cone crusher jams are usually caused by sudden failures, which may seriously affect production and reduce the service life of equipment and components. Let's take a look at the causes of crusher jams.

　　1, blocking material
1. The cone crusher feeds too much or the feed characteristics do not meet the requirements, it will cause the cone crusher to block the material, make the crusher work too much, the circuit will automatically protect and s, and the cone crusher may even be stuck The situation of forced shutdown.
　　 2. When iron blocks or other hard objects enter the crushing cavity of the cone crusher, it will also cause the cone crusher to block the material.

　　 2, the spindle is broken and stuck
　　 1. Improper use of the cone crusher causes the main shaft to break. For example, in order to obtain a desired discharge fineness, the discharge port is constantly tightened. If an unbreakable object enters the crushing cavity, it will have a significant impact on the main shaft, causing the main shaft of the cone crusher to break and become stuck.
　　2. When the cone crusher is continuously overloaded, despite the overload protection device, it is impossible to completely avoid damage to the equipment, and the main shaft is easy to break and cause the equipment to jam.

　　3, the moving cone and adjusting sleeve are stuck
　　 1. When the cone crusher is running under load, the adjusting sleeve will rotate with the cone due to the pressure loss of the hydraulic station. If the staff fails to find out and deal with it in time, it will cause the adjustment sleeve to be jammed and cause the cone crusher to s.
　　2. The reasons for the jamming of the adjusting sleeve may be poor thread lubrication, abrasion of the adjusting cover seal or the dust cover seal, the threading of the adjusting sleeve and the supporting sleeve, or the cone crusher is overloaded for a long time.
