We do a good job in maintaining the purchased coal washing equipment. For example, lubrication is important for coal washing settings, which can reduce wear and prolong service life, ensuring the safe and efficient operation of the coal washing machine. And what is the purpose of doing so? Next, I will explain it to everyone, hoping it will be helpful to you.

　　The first point is to reduce the wear of coal washing machinery. There is a certain strength of lubricating film between the friction surfaces to support the load, avoiding or reducing direct contact with the metal surface, thereby reducing various degrees of adhesive wear on the contact surface of the coal washing machine, such as plastic deformation, melting welding, shearing and re bonding;

　　Secondly, to reduce the vibration of coal washing equipment, lubricants can convert the mechanical energy of impact vibration into hydraulic energy, which plays a role in reducing impact and absorbing noise.

　　Thirdly, control friction by adding lubricant between the friction surfaces of the coal washing machine to form a lubricating film, reducing direct metal contact between the friction surfaces, lowering the friction coefficient, reducing friction resistance, and also reducing the power consumption of the coal washing equipment;

　　Fourth point: Sealing isolation, lubricating grease covering the friction surface or other metal surfaces of the coal selection machine, isolating the contact between water, moisture, and other harmful media and the metal, thereby reducing corrosion and wear, preventing rust, and protecting the metal surface;

　　Fifth point: Rust and corrosion prevention, which isolates the metal surface of coal preparation machinery from the air and prevents oxidation;

　　Point 6: Cooling and cooling. Lubricants can reduce the friction coefficient of coal washing machines and reduce the generation of frictional heat;

　　Point 7: Assist in cleaning stains, metal powder particles, and other foreign objects on the friction surface of coal washing equipment;

　　In summary, the function of lubricating coal washing equipment is to effectively extend the service life of the equipment. When using this equipment, we also need to maintain it in a timely manner.
