Stone crusher is the most important equipment for mining work, in the daily use of the process must strengthen its maintenance, reduce the wear and tear in the process of use. We can only familiarize ourselves with the forms and principles of wear and tear of various mining machinery crusher, so that we can better maintain the operation of the stone crusher, extend its service life, and bring more profits to customers.

Because the roughness and hardness of the surface of the parts are different, in the process of mutual friction will make some free particles sliding between them, thus causing abrasive wear between the parts. Abrasive wear on the degree of wear of mining machinery to a large extent, depending on the hardness, shape, size and distribution of abrasive particles and other factors, and friction with each other parts of the relative value of the material hardness, abrasive hardness value of the higher will be on the parts of the friction of the more serious, on the whole mining work caused by the impact will also be greater.

Stone crusher parts in the long-term repeated shear stress, to reach the fatigue limit of the material, it will make the crusher parts because of fatigue and wear. Mining machinery and equipment of the shear stress wear all the time, long-term repeated action will cause more obvious wear, due to the different strength of the material, the softer material will break, and leave some pockmarks, there will be cracks.

Parts in the case of load action, the contact point of the greater shear stress will plastic deformation, making the contact place adhesion, so as to connect together, resulting in parts wear. In the process of operation, the part is subjected to greater pressure, friction when the temperature is also higher, it will cause the contact surface because of direct contact without lubrication becomes dry, increasing friction, resulting in the softening of the metal surface, resulting in adhesive wear.

In the process of use, some chemical substances and metal chemical reaction, produce some acidic substances, corrosion of metal materials. Stone crusher parts because of corrosion and the formation of part of the metal corrosion, these substances adhere to the mechanical parts, in the friction and wear process of these substances adhesion is not solid, it will be linked to the metal material and the metal surface of the oxidized film is peeled off, so that the metal surface is exposed to the air, resulting in the corrosion of new surfaces and wear and tear, resulting in the intensification of the wear and tear of metal surfaces. Mining machinery parts in the vapor pressure of the working conditions, the liquid flow is constantly impact, so repeated pressure makes in the metal surface erosion and wear.
