The multi-cylinder hydraulic cone crusher can crush all kinds of materials with medium hardness or above, which finished product has good particle shape, uniform particle size and low fine powder content. It is widely used in metal mining, metallurgical industry, construction industry, cement industry, sand and gravel industry and other projects However, there are also many customer feedbacks that even when the cavity is full, the production capacity is still not high enough to achieve the ideal state. On the premise of ensuring the particle size of the ore, this article will introduce how to improve the production capacity of the crusher.
1. Feeding
(1). Sufficient feeding
When the multi-cylinder hydraulic cone crusher crushes the material, it should be fully fed and run in a full cavity. After the material enters the crushing cavity from the feeding port, it is crushed by the mutual impact extrusion, grinding and rubbing of the eccentric shaft and the concave. A small amount of feed has adverse effects, it not only will not reduce the burden on the crusher but will cause its capacity to be damaged and the grain shape to be poor.

(2). Uniform feeding
When feeding, it should be uniformly fed to avoid the situation that large-diameter stones are concentrated on one side and small-diameter stones are concentrated on the other side. The uniform feeding of the multi-cylinder hydraulic cone crusher will balance the force of the material and make the crusher work smoothly. Once the feeding is uneven, due to the abnormal increase in bulk density, compaction and blockage of the side where the small-sized stones are concentrated are prone to occur, causing the adjustment ring to jump. Faced with the beating of the adjustment ring caused by the blockage, the operator will be forced to increase the parameters of the discharge port, resulting in an increase in the particle size of the product. In the long run, it will also cause problems such as damage to the adjustment ring, resulting in greater production losses.
(3). Uniform particle size
The uneven feed particle size will seriously affect the working ability of the equipment, and will seriously reduce the production capacity, and the product particle size will not meet the required requirements. Because when the particle size and geometric size of the material are very different, the small material will protect the large material from being crushed. The particle size segregation of the material in the crushing cavity of the multi-cylinder hydraulic cone crusher is serious, that is, the phenomenon of fine particle protection. The input material cannot be completely crushed, resulting in uneven discharge. Therefore, when crushing the material, it should be ensured that the particle size of the feed is uniform.
2. Discharge
The size of the closed side discharge opening of the multi-cylinder hydraulic cone crusher will directly affect the capacity. Under normal circumstances, the larger the size of the closed side discharge port, the greater the capacity of the multi-cylinder hydraulic cone crusher, but the content of needle-like materials in the product increases. On the contrary, the smaller the size of the closed-side discharge port, the smaller the capacity of the multi-cylinder hydraulic cone crusher, but the quality of the crushed products will be relatively better. In order to ensure the capacity and material type of the multi-cylinder hydraulic cone crusher and effectively improve the crushing efficiency, the operator should timely detect the change in the size of the closed-side discharge port and adjust it accurately.
3. Lubrication
During the operation of the lubricated multi-cylinder hydraulic cone crusher, there will be friction between the surfaces due to mutual contact and relative movement. This frictional work is converted into heat, which is not good for the operation of the machine, reducing the production capacity, and friction is one of the causes of wear and tear of parts. Therefore, timely improvement of the friction condition of the surface of the parts and reasonable lubrication of the multi-cylinder hydraulic cone crusher can effectively improve the work efficiency and prolong the service life. In this link, on the premise of ensuring the oil quantity and oil quality, carefully check the operation of the oil pump, regularly clean the descaling device and check whether various filter elements need to be replaced, check whether there are copper scraps on the oil return filter, etc., The oil passage of the lubricating system should always be kept unobstructed, the oil quality should be clean, and there should be no seepage or leakage, so as to ensure the normal operation of the crusher.
4. Maintenance
The maintenance of the multi-cylinder hydraulic cone crusher is extremely important and regular work. If the crusher is damaged frequently, it will directly reduce the production capacity. In the actual production process, there will be more or less a series of problems. Professionals should do a good job in daily operation, maintenance, maintenance and other work to reduce the economic loss caused by equipment failure and shutdown. Listed here are several common fault phenomena, causes and solutions of multi-cylinder hydraulic cone crushers, which will be analyzed and solved according to the specific situation.
The multi-cylinder hydraulic cone crusher has large crushing ratio, high efficiency, low power consumption, and high qualified rate of product particle size. It is widely used in major mining areas and stone quarries. In the actual production process, we hope that everyone will increase production capacity, effectively increase production capacity, and create higher profits.
