The cone crusher adopts a structure with a fixed spindle and an eccentric sleeve that rotates around the spindle, which can withstand greater crushing power.Reasonable coordination of eccentricity, cavity shape and motion parameters has greatly improved production capacity and work efficiency.However, if there is a problem with the equipment, uneven discharge may occur, which will not only reduce the production efficiency of the cone crusher, but also affect the particle size of the product.So why does this problem occur?How to solve it?

What is the cause of uneven discharge of cone crusher?

1. The feeding is not in line with the requirements

The material particles are too large and excellent.When there are materials with too large or excellent particles in the crushing chamber, the particle size segregation of the materials in the crushing chamber of the cone crusher will be serious, and the input materials cannot be completely broken, resulting in uneven discharge.The material contains too much water.When materials with too much water content enter the crushing chamber of the cone crusher, they will meet and stick together, causing the material in the crushing chamber to be clogged, reducing the crushing capacity of the equipment on the material, resulting in uneven discharge.

2. Incorrect feeding

Too much material is fed.When there is too much material put into the crushing chamber, it is easy to clog the material in the crushing chamber, occupying part of the space in the crushing chamber so that the material crushing space is reduced, and the particle size of the broken material may be uneven.Uneven feeding.Uneven distribution of feed along the four sides of the crushing chamber of the cone crusher will cause uneven force on one side of the equipment, affecting the crushing effect of the equipment on the material, resulting in uneven crushing of the material.

3. Incorrect parameters

The size of the mine discharge port is improper.When the size of the ore discharge port of the cone crusher is improper, it is easy to cause the material that has been broken to be discharged too late, causing blockage of the material, affecting the crushing of the material, exacerbating the blockage of the material, and causing uneven material crushing.The voltage is too low.When the working voltage at the crushing site is too low, it cannot provide production conditions for the normal crushing of the cone crusher, and the crushing power is insufficient, resulting in uneven particle size of the broken product.

The specific solutions are as follows：

1.Correct feeding

Ensure that the hardness of the material is suitable for the cone crusher model, check the particle size of the finished product in time, and adjust the size of the ore discharge port.If a material with too large particles is put into the cone crusher, the locking force of the cone crusher will be insufficient, causing the adjustment ring to beat.Therefore, the particle size of the incoming material should be strictly controlled, and ore that does not meet the requirements of the material broken by the cone crusher should be prohibited from entering the crushing chamber. On the other hand, attention should be paid to prohibiting non-broken objects such as iron and impurities from entering the crushing chamber.If the feeding of the cone crusher is uneven, it can easily lead to uniform force on the equipment, which causes the beating of the adjustment ring. Therefore, the feeding is within the range of 360° of the crushing chamber when feeding, and the distribution is uniform.

2.Do a good job of equipment inspection

If the adjustment cap is not locked when it is locked, it will cause beating. Therefore, a comprehensive inspection must be carried out before the cone crusher is started, and if it is found to be loose, it must be tightened in time to ensure the efficient operation of the cone crusher.The reasons for the loosening of the adjustment sleeve of the cone crusher are improper ore discharge port, or the rolling mortar wall and the crushing wall are too thick.Therefore, in the production process, we should do a good job of equipment overhaul and maintenance, pay attention to the production of equipment, and find out the cause of the failure in time and solve it.

3.Reduce component wear

The locking bolt of the cone crusher plays the role of fixing the equipment, and when the locking bolt wears out, it can easily cause the adjustment ring to beat.Therefore, the wear of locking bolts should be minimized in production.If the thread of the adjustment ring and locking ring of the cone crusher are severely worn, it will also cause the adjustment ring to beat.Therefore, the wear of the thread should be reduced in production and a reasonable gap between the adjustment ring and the locking ring should be ensured.
