According to the different grinding medium and grinding materials, the mill can be divided into: Ball Mill, column grinder, Rod grinder, pipe grinder, self-grinder, swivel roller grinder, vertical grinding, multi-layer vertical grinding, vertical roller grinder, disc grinder, DMC grinder and so on. In the production of ceramic industry, intermittent ball mill is widely used, the grinding effect can be divided into two parts, one is the grinding effect between the grinding body and the grinding body and the simplified, the second is the impact of the grinding body drop, in order to improve the grinding efficiency, it is necessary to start from these two aspects. The "multi-shredding and less grinding" technology and technology of metal ore is a topic that has been mentioned for many years, reducing the grinding granularity of ball mill, adding a section of pre-grinding or ultra-fine shredding technology in front of Ball mill, which is an important technological innovation of energy saving and consumption reduction in mining enterprises. The research of grinding technology of grinder is one of the key points in mineral processing engineering technology. The grinding process is to squeeze, roll, shock and grind the ore by using the energy of the mill, so that the useful mineral monomer in the ore cleavage (away), which is conducive to the selection of other processes in the next stage.
