Ball mill is the key equipment of the material to be grinded after being crushed. The grinding effect of ball mill is mainly that the grinding body has the impact of the material and grinding the material.

How to improve the composition characteristics of grinding grain size should be paid much attention to.From the perspective of the grinding process, grinding is a necessary mineral preparation prior to enrollment job that's main purpose is to prepare the candidate for the beneficiation of mineral monomer dissociation is sufficient and appropriate beneficiation required mineral particles.Because in the ore dressing process, any mineral processing methods is limited by particle size and size range will be effective constraint. When beyond the size range, the mineral particles will be hard to be in the effective separation.

Therefore, how to make mineral sufficient monomer dissociation is the main role of grinding, and how to make the particle size of grinding is more suitable for dressing requirement is the second purpose of grinding.Making the grain size is suitable for the grinding requirements of ore dressing, and is related to the problem of ore dressing effective sorting problems of the concentration. And it is also one of the important standards to evaluate the quality of the grinding.Steel ball size and the selection of proportioning in grinding process are also very important. Make the particle size of grinding suitable for processing requirements, at the same time reduce the harmful of crushed graded levels; this is also the problem of how to better achieve the grinding purposes. This is also one of the important problems of grinding media work theory.
