With the development of crushing market, the demand for crushers is increasing year by year. At present, the cone crusher has become one of the mainstream products in the crushing machinery. The cone crusher is well known for its unique lamination crushing principle, which is especially suitable for the crushing of hard materials. But in the actual production, the failure and loss caused by improper operation and other reasons also occur from time to time, so in the daily production, which operation will cause the wear of the cone crusher crushing chamber?

1.High hardness of ore
In the operation process of cone crusher, if the hardness of the crushed material is too high or the strength is too large, it will bring abnormally high impact force and impact force to the crushing chamber, which will accelerate the wear of the crushing chamber and even damage the crushing chamber for a long time. Therefore, when feeding the cone crusher, pay special attention to the hardness and particle size of the material within the design range of the cone crusher.

2.Too much residual material in the cavity
As we all know, the crushing principle of cone crusher is the laminated crushing of materials. Under normal circumstances, there is a little material accumulation in the crushing chamber in the process of cone crusher operation to protect the crushing chamber from material damage. However, if the materials are piled up too much in the crushing chamber, the effect will be just the opposite: if the materials are piled up too much in the crushing period, there will not be enough space for the materials to be crushed to form crushing. At this time, the crushing machine will automatically increase the crushing force to complete the full crushing of the materials. If the pressure is too high, the crushing chamber will be easily damaged. Therefore, the material accumulation in the crushing chamber should be done according to the capacity, and proper stacking should not cause damage to the crushing chamber due to excessive stacking.

3.Crushing chamber blocked
When the crushing equipment is working, if the phenomenon of crushing cavity blocking occurs, it will seriously affect the crushing efficiency and the final output, and it will also bring serious wear to the crushing cavity. When the cone crusher encounters the situation that the crushing chamber is blocked, the materials cannot be discharged from the discharge port quickly, and the materials will accumulate in the crushing chamber. At the same time, the fixed and moving cone parts will continue to break the materials, which will cause the materials in the crushing chamber to be continuously impacted and collided, forming the abnormal wear and damage of the crushing chamber.

4.Poor quality of crushing chamber
The material of the crushing chamber is closely related to the wear of the crushing chamber. The poor toughness and wear resistance of the material of the crushing chamber will be very low, and the service life will naturally be very short. Especially when crushing hard materials, it is easier to wear the crushing chamber. Therefore, when choosing the material of crushing chamber, we should try to use the original material configured by the original factory to reduce the wear consumption caused by the material.

5.Incorrect feeding mode
Whether the materials are put in correctly is also an important factor to cause the wear of the crushing chamber. When feeding the cone crusher, attention should be paid to put the materials into the dividing plate first. If the material enters the crushing chamber directly without passing through the dividing plate, the steepness and gradient of the material will be too high, the inertia and impact force of the material will increase, and the crushing chamber will be easily damaged by the material, causing great damage to the conical crushing chamber. Therefore, when the cone crusher is feeding, it is necessary to first put the materials into the dividing plate, which will put the materials into the crushing chamber.
