Sand making machines are widely used in ores, building materials, cement, chemical industries and other industries. In order to ensure the normal operation of the sand making machine and extend its service life, maintenance is a very important link. How to improve the life of sand making machine?

　　The main shaft of the sand making machine is the main component for transmitting power and bears the crushing force and vibration force of the entire equipment. Therefore, the strength and stiffness requirements of the spindle are very high, and it is generally made of alloy steel.

　　The impeller is the core component of the sand making machine and is responsible for high-speed rotation, impact and crushing of materials. The shape, size and material of the impeller directly affect the crushing effect and service life of the sand making machine.

　　The transmission device is the component that connects the motor and the spindle and is responsible for transmitting the power of the motor to the spindle. The stability and reliability of the transmission device are crucial to the normal operation of the sand making machine.

　　The bearing is a key supporting component of the sand making machine and bears the pressure and friction of the main shaft and impeller. The lubrication and maintenance of bearings have an important impact on the service life of the sand making machine.
