1. Blockage and jamming:
The cone crusher feeds too much or the feed properties do not meet the requirements, which causes the cone crusher to jam, which will make the crusher's working current too large, and the circuit automatically protects and stops the machine. It may even cause the cone crusher to jam and be forced to shut down.
When iron blocks or other unbreakable objects enter the crushing chamber of the cone crusher, it will also cause the cone crusher to jam or even the equipment to jam.
2. Spindle breakage and jamming:
Improper use of cone crusher is one of the main causes of spindle breakage. In order to achieve the required discharge fineness, the discharge port needs to be continuously tightened. If unbreakable objects enter the crushing chamber, the spindle will have a slight impact, causing the spindle of the cone crusher to break and jam.
When the cone crusher is in overload operation for a long time, although there is an overload protection device, it cannot completely avoid damage to the equipment. The spindle is prone to breakage and the equipment is jammed.
3. Moving cone and adjustment sleeve are stuck:
When the cone crusher is running under load, the locking fails due to the loss of pressure in the hydraulic station, and the adjustment sleeve will rotate with the moving cone. If the staff on duty does not find and deal with it in time, it will cause the adjustment sleeve to get stuck, resulting in the shutdown of the cone crusher.
The reasons for the adjustment sleeve to get stuck may also be poor thread lubrication, wear of the adjustment cap seal or dust cover seal, abrasion of the adjustment sleeve and support sleeve threads, or long-term overload operation of the cone crusher.
