The service life of crusher copper bushing is affected by many factors, usually around 3 months to 3 years. The following is a specific introduction:

Working environment:

Dust concentration: If the dust concentration in the working environment of the crusher is high, the dust will easily enter the gap between the copper bushing and the shaft, which will wear out the copper bushing and the shaft and reduce the service life of the copper bushing. For example, in some quarries, dust is flying, the wear of the crusher’s copper bushing will be accelerated, and may need to be replaced after about 1 year of use.

Corrosive media: If the materials handled by the crusher are corrosive, or there are corrosive gases or liquids in the working environment, it will have corrosive effect on the copper bushing, which will shorten the service life of the bushing. For example, in some chemical material crushing scenarios, corrosive substances may lead to the service life of the copper bushing is only a few months.

Equipment operating parameters:

Load size: The crusher crushes materials with high hardness and large block size, which will increase the load borne by the copper bushing and intensify the wear of the copper bushing. Long-term high load operation, the copper bushing may be damaged in 1-2 years. On the contrary, crushing softer, smaller pieces of material, the service life of the copper bushing will be relatively long.

Speed: High speed will increase the friction between the copper bushing and the shaft, generating more heat and accelerating the wear and aging of the copper bushing. For the crusher with high rotational speed, the service life of copper bushing may be shorter than that of the equipment with normal rotational speed.

The quality of the copper bushing itself:

Material: different materials of copper bushing wear resistance, corrosion resistance and other properties are different. For example, tin bronze material copper bushing has better wear resistance and corrosion resistance, relatively long service life; and ordinary brass material copper bushing performance is slightly worse, the service life may be shorter.

Manufacturing process: the manufacturing process of the copper bush, high dimensional accuracy, good surface finish, and the shaft with a closer fit, can reduce friction and wear, longer service life. On the contrary, the manufacturing process of rough copper bushing is prone to defects, the service life will be affected.

Maintenance situation:

Lubrication: good lubrication can reduce the friction between the copper bushing and the shaft, reduce wear and prolong the service life of the copper bushing. If regular lubrication and maintenance of the crusher copper bushing is carried out and the lubricant is replaced in time, the service life of the copper bushing may reach 2-3 years; while neglecting the lubrication and maintenance, the copper bushing may be damaged in a few months.

Routine inspection and maintenance: Regular inspection of the crusher, timely detection and treatment of abnormalities in the copper bushing, such as wear, looseness, cracks, etc., can avoid further deterioration of the problem and extend the service life of the copper bushing. On the contrary, if daily inspection and maintenance are not carried out, small problems may gradually develop into big problems, leading to early scrapping of the copper bushing.
