Large ball mill

Large Ball Mill

Applications: It is widely used in mining, cement, metallurgy, building materials, ceramics, medicine and other fields.

Large Ball Mill Details

A large ball mill is known for its large processing capacity and long daily operation time, so it is also called a large scale ball mill or large capacity ball mill. The large ball mill is especially suitable for large-scale grinding production. It adopts two bin grinding, which is more energy-saving and environmental protection. The large scale ball mill adopts the horizontal cylindrical rotating structure, and the appearance design is more reasonable.

After the upgrade of new components, the material of large ball mills and the performance of internal wearing parts have been further improved, with more reliable grinding performance. Large capacity ball mills are common in large-scale mineral processing production lines and big cement plants, with more economic benefits.

The grinding process is the main link of electrical energy consumption in the entire grinding production line. The grinding operation has the characteristics of large installation power and high energy consumption, and ultimately determines the energy consumption of the entire production line.

Taking a large-scale beneficiation plant as an example, as the mining continues to deepen, the grade of the original ore continues to decline, and the processing capacity of the grinding operation also increases. At this time, it is necessary to increase the production capacity of the ball mill machine. If the number of ore ball mill equipment is increased, it will lead to an increase in floor space, and the grinding production process will become complicated. This will lead to problems such as complicated operation and management, increased auxiliary equipment, and increased capital investment.

With the deepening of research, it was found that the energy consumption per unit material production and the wear rate of large diameter ball mill is lower than the plan of multiple small ball mill.

The use of big ball mill can also reduce the floor area of the equipment, simplify the process, facilitate the management and maintenance, and facilitate the automatic management of the process. In large-scale grinding operations, the use of big ball mill has reduced the cost of beneficiation, making some low-grade ore once used, which is conducive to the comprehensive utilization of resources, so it is favored by large-scale beneficiation plants and cement plants.

Performance Advantages of Large Ball Mill

  • The structure design of the large ball mill is very reasonable, simple and efficient, easy to operate and maintain, easy to disassemble and replace, save the workload, improve the efficiency in unit time.
  • The large scale ball mill adopts an advanced lubrication system, which is conducive to improving the running state of lubricated components, effectively reducing the heat of friction production, and ensuring the efficient and safe operation of the equipment.
  • Large ball mill can adopt dry grinding and wet grinding, which can be selected according to the needs of users, with high production flexibility and even fineness of finished products.
  • The large ball mill adopts rolling bearing, which has large capacity, low failure rate, more stable operation and long service life.
