Ball mill grinding operations in the importance of beneficiation, ore crushing grinding operation is a continuation of the process is divided before the election an important part of preparation work. Grinding operations not only for mineral industry, but also in construction, chemical and power industry sectors are also widely used. In addition to handling some of the sands outside of all the concentrator, almost all grinding operations. In the mineral industry, as useful for fine-grained ore minerals embedded in the fabric, the order to feel the pulse of rock removed from the ore, and to a variety of useful minerals separated from each other, must be finely ground ore to, and sometimes even wear to the following.
Grinding fineness and mineral indicators are closely related. To some extent, the recovery rate of useful minerals with grinding fineness decreases. Therefore, an appropriate reduction of ore grinding fineness of useful minerals can improve the recovery rate and production. Grinding power consumption of the total power consumption accounts for more than concentrator. Therefore, the grinding operation in the beneficiation process plays an important role. In clean coal technology, coal-water slurry for grinding operations, oil coal slurry, coal slurry pipe, pulverized coal combustion and utilization of coal associated minerals and so on. In heavy medium coal preparation plant, the grinding operation is used to prepare heavy-medium coal preparation used in increasing quality.
