Stone crusher is the most important equipment of mining work，in everyday use process must strengthen its maintenance, reduce wear and tear in the course. We only familiar with the forms and principles of wear and tear of various mining machinery crusher, can better safeguard the stone crusher run, extending its life, to bring customers greater profits.

As a result of surface roughness and hardness of the parts are different, in the process of mutual friction will make some free particles slide in which room, thereby causing abrasive wear between the parts. A large extent, abrasive degree for wear of mining machinery depends on hardness, shape, size and distribution of the abrasive grains, among other factors, and relative hardness values of mutual friction parts and materials, higher hardness values of abrasive grains more serious friction of the parts, impact on the whole will be greater due to mining work.

In the long-term effects of repeated shear stress, stone crusher parts reaches fatigue limit of the material, it will make the crusher parts because of fatigue and wear. Shear stress wear and tear of mining machinery and equipment always exist, long-term repeated effects will cause more obvious wear, due to the different of the material strength, a relatively soft material will be broken and leave some pitting, appear cracks.

Parts in the circumstances of load acts, contact points of the larger shear stress will be plastically deformed, making contact with place adhesions, thereby together cause parts to wear. In operation, some parts bears pressure is relatively large, when friction, the temperature is relatively high, it will cause the contact surface because there is no lubrication direct contacting becomes dry, increase the friction, cause the metal surface is softened, produce adhesive wear.

During use, certain chemical substances react chemically with the metal to produce a number of acidic substances, corrosive to metals material. Stone crusher parts formed part because of corrosion form some metal corrosion, these substances adhesions on mechanical parts, in the process of friction and wear these substances adhesions is not solid, it will joint and several metals and metal surface oxide film is peeled off, so that the metal surface exposed to the air, causing the new surface corroded and wear, resulting in increased wear of metal surfaces. Mining machinery parts in the working conditions of the vapor pressure, constantly flow impact, so repeatedly have a pressure makes the erosive wear on the metal surface.
