In recent years, the continuous improvement of the situation, we gradually mastered the repair knowledge of ball mill, ceramic ball mill is widely used in mineral processing, building materials, chemical industry grinding medium hardness of ore and other materials, according to the grinding mode ball mill can be divided into dry and wet ceramic ball mill, according to the discharging methods different, it can be divided into lattice type and overflow type ceramic ball mill; according to the different grinding media ball mill can be divided into milling ceramic ball mill, rod mill, ceramic ball mill; according to the structure is divided into traditional ceramic ball mill, straight tube energy-saving ceramic ball mill and cone energy-saving ceramic ball mill three. Ceramic ball mill adopts sliding bearing to replace the traditional, save power consumption.Domestic ceramic industry is developing rapidly, especially the ceramics industry, large enterprises are constantly emerging. In order to reduce the energy consumption to improve the use of land area ratio, production capacity and energy consumption of each enterprise grinding equipment for all kinds of demands a very high, so the labor intensity is low, high output, so the ball mill is widely used. In the building ceramics industry, due to continuous wet type with high yield, low energy consumption, less occupied area, high degree of automation, low labor intensity, low environmental pollution, and application of wet ball mill will have a hitherto unknown achievement.The cement, paint, ceramic, metallurgical, chemical, medicine, food and magnetic materials are related to super fine powder processing equipment, and ball mill is key equipment for grinding materials being broken. Super fine technology of ball mill can be widely used for processing of various mineral and raw materials. Annually, developed countries invest sufficient funds in powder processing application and research to support the study of...
