Application Areas: The ball mill is typically employed in cement production, manufacturing of silicate products, development of new building materials, production of refractories, manufacture of fertilizers, processing of black and non-ferrous metals, production of glass ceramics, and various other applications.
The ball mill is composed of main parts such as feeding part, discharging part, rotating part, transmission part (reducer, small transmission gear, motor, electric control). The hollow shaft is made of cast steel, the inner lining can be removed and replaced, the large rotary gear is processed by casting gear hobbing, and the cylinder is inlaid with a wear-resistant lining plate, which has good wear resistance. The machine runs smoothly and works reliably.
The main body of the ball mill includes a cylinder, which is inlaid with a lining made of wear-resistant materials, a bearing that carries the cylinder and maintains its rotation, and also has a driving part, such as a motor, and transmission gears, pulleys, V-belts, etc.
1. Cylinder: The cylinder is the main part of the ball mill. It is a circular device made of welded steel plates of a certain thickness. When working, it not only bears the static load of its own grinding medium, but also is affected by the alternating stress generated by the grinding medium impacting the rotation of the cylinder. Therefore, it must have sufficient strength and rigidity.
2. Bearing: The bearing is the supporting part of the ball mill, which carries the mass of the rotating part of the ball mill and the impact load of the grinding medium. Moreover, the rolling bearing is used instead of the sliding bearing, which has low running resistance and significant energy saving. It is also necessary to do a good job of lubrication and heat dissipation.
3. Transmission device: The ball mill is a heavy-duty, low-speed and constant-speed machine. Generally, the transmission device is divided into two forms: edge drive and center drive, including motor, reducer, drive shaft, edge drive gears and V-belts, etc.
4. Feeding and discharging device: The feeding and discharging device of the ball mill is mainly composed of an end cover with a hollow journal, a joint feeder, a fan-shaped liner and an inner sleeve of the journal.
1. Strong adaptability
The ball mill has strong adaptability, can grind most materials and mix them uniformly, and can adapt to the operation in different environments.
2. Meet different needs
It can operate continuously, and the production capacity can reach more than 200 tons per hour, which meets the needs of modern industrial large-scale production.
3. Strong sealing
The ball mill equipment has a good sealing device, strong sealing, and can be operated under negative pressure to prevent dust from flying.
4. The material has high wear resistance
The casting turning device is adopted, the hollow shaft is made of cast steel, the steel plate is planed, and the flanges at both ends of the cylinder are made of large CNC cylinder lathes. The special processing technology can fully meet the requirements of concentricity and has good wear resistance.
5. Low energy consumption
The ball mill adopts a wave-type annular lining plate, which increases the contact surface between the ball and the ore, strengthens the grinding effect, and has the ability to lift the ore, reducing energy consumption.
6. Long bearing life
The bearings used in the ball mill are not only advanced in material, but also refined in the manufacturing process, which increases the service life by about 15% compared with the traditional ball mill bearings.

The main body of the ball grinding mill is a low-speed rotating cylinder mounted horizontally on two large bearings. The ball mill is decelerated and driven by a motor through a reducer and surrounding large gears, or a low-speed synchronous motor is directly decelerated through a surrounding large gear to drive the rotating part to rotate. The cylinder is equipped with steel balls with appropriate grinding media. The grinding medium is lifted to a certain height under the action of centrifugal force and frictional force and falls in a state of throwing or venting. The ground material continuously enters the inside of the cylinder through the feeding port, is crushed by the moving grinding medium, and is discharged out of the machine through the force of overflow and continuous feeding for the next process processing.
