Reasons for serious oil dumping of cone crusher and corresponding solutions

Cone crusher is a kind of commonly used mining machinery and equipment, which is mainly used for crushing operation of stone and ore. However, in the process of use, sometimes there will be serious oil dumping problems, which not only affects the normal operation of the equipment, but also may cause safety hazards. In the following, we will discuss the reasons for serious oil dumping of cone crusher and the corresponding solutions.

First, the cone crusher serious oil dumping reason analysis

1. Failure of sealing device

The sealing device of the cone crusher is the key component to prevent lubricant leakage. 

Seal failure can be caused by aging of the seal material, wear and tear, improper installation or design 

defects, etc. When the seal fails, the lubricant will leak along the seal gap. When the sealing device fails,

 the lubricant will leak along the sealing gap, leading to the phenomenon of oil dumping.

2. High lubricant pressure

During the operation of the cone crusher, the lubricating oil needs to maintain a certain pressure to

 ensure the lubrication effect. However, if the lubricant pressure is too high, it will increase the risk of

 lubricant leakage. Excessive pressure can be caused by lubricant pump failure, regulator failure, or oil

 line blockage.

3. Unreasonable design of lubrication system

The design of lubrication system directly affects the lubrication effect of cone crusher. If the lubrication

 system is not reasonably designed, such as improper layout of the oil circuit, insufficient capacity of the

 oil pool or poor oil return, etc., it will lead to excessive accumulation of lubricating oil in the body, which

 will lead to the problem of oil dumping.

Second, the cone crusher oil dumping problem solution measures

1. Strengthen the maintenance and replacement of the sealing device.

Regularly check the operation status of the sealing device, replace the aging and worn seals in time to 

ensure the integrity of the sealing device. At the same time, optimize the design of the sealing device to

improve the sealing performance and reduce the risk of oil dumping.

2. Adjust the lubricant pressure and flow

According to the actual operation of the equipment, reasonable adjustment of lubricating oil pump 

pressure and flow, to ensure that the lubricating oil in the body of the distribution of uniformity, to avoid

 excessive pressure caused by the dumping of oil problems.

3. Optimize the design of lubrication system

For the unreasonable design of the lubrication system, it can improve the performance of the lubrication

 system and reduce the occurrence of oil dumping phenomenon by improving the layout of the oil 

circuit, increasing the capacity of the oil pool or optimizing the oil return system.
