Coal ball mill is the equipment used for grinding and drying coal with different hardness. It is mainly composed of feeding device, principal axis, rotating part, transmission part, discharging part, high-pressure starting device and lubrication system. The coal grinder is also widely used to break various hardness of coal in cement industry, metallurgy industry and chemical industry and so on.
Cement ball mill is a grinding equipment for cement materials in the cement plant. Feeding size: â?¤25mm Capacity: 33-85t/h Functional advantages: Uniform abrasive, low energy consumption. It mainly used in cement plants, building materials, metallurgy, electric power, and chemical industry, grinding all kinds of cement clinkers and other materials. Email: info@ballmillssupplier.com
Swivel type lead-bronze bushed trunnion bearings are generally furnished on large diameter ball Mills. The bearing swivels are of Meehanite metal spherically turned outside and bored and faced inside to receive the removable bushing. The bushing is bored and scraped to fit the mill trunnion. The bushing is provided with end flanges thus assuring that the trunnion flanges run against a bronze face. On smaller mills rigid or swivel type bearings support the mill trunnions. The lower half of such bearings are lined with bronze or a special mill babbitt which is peened in place and bored to fit the trunnion. In all cases a low bearing pressure is maintained to assure freedom from overheating, long life and minimum maintenance. They are designed to provide support to the mill proper, its media and pulp load. Trunnion bearings are generally supplied with seals for use with a circulating oil lubrication system. They can be designed to accommodate block grease or oil with wool waste. For special applications trunnion bushings can be furnished constructed of Micarta to allow water lubrication or oil lubrication. In many dry grinding applications, or where heat is developed, the trunnion bearings can be furnished for water cooling. This system carries away the excess heat transmitted through bearings and protects them.
The hollow shaft is an important part of the ball mill that carries the rotation of the ball mill barrel. In terms of technology, there must be no casting defects such as pores and sand holes in the neck of the ball mill in contact with the spherical tile of the ball mill and the arc neck in contact with the cylinder; in terms of processing, the part in contact with the spherical tile needs to be ground after processing to ensure that Precision and finish, so its requirements for the casting process are very high. We could provide the OEM services for the Hollow Shaft, please send drawings to us freely.

Ball mills are preferred when a product of less than 150 microns is desired. According to the factory capacity and the projects of our customers, together with our technical team, we calculate the required mill size together and put into operation the grinding division.
Ball mill is the key equipment for secondary grinding after crushing. And it is suitable for grinding all kinds of ores and other materials, no matter wet grinding or dry grinding. Besides, it is mainly applied in many industries, such as ferrous&non-ferrous metal mine, building materials, chemical, electric power, coal, traffic, light industry, etc. In our company, this series of high-efficiency ball mill adopts rolling bearing support instead of sliding bearing support with bearing bush. Therefore, it can save energy by 10-20%. According to different discharging ways, it can be divided into two kinds, grate type and overflow type.
Ball Mills are used for grinding with dry or wet systems.Speacial designs according to process and materials 3000x6000
