The support points of many machine rotating parts are easily polluted by dust, resulting in increased frictional resistance and increased mechanical wear. During the maintenance and lubrication of equipment, it is especially necessary to prevent particle wear. Particle wear is the abnormal wear caused by abrasive particles (fine sand, iron filings, dust, etc.) on the two friction surfaces, which is extremely serious for mechanical wear.

 

Due to poor maintenance and lubrication management, new dust remains at the lubrication points during installation, poor sealing causes dust to invade from the outside, poor grease management causes pollution, poor running-in produces metal powder during initial operation, and poor lubrication systems such as filtration devices can also cause Particle wear.

 

Particle wear has a great influence on the life of stone machinery. According to statistics, wear and tear in industry accounts for about 50%. It is regarded as the enemy of industrial machinery damage and should be given enough attention. In particle wear, the source of particles is related to maintenance operations and lubrication quality as well as the dust content of the atmosphere.
