Sand mill in the slurry processing, due to the grinding needs to achieve the discharge particle size and the size of the material itself, in order to achieve efficient grinding effect, usually take different grinding methods and grinding program.

For its own particle size is very large materials, in the grinding process, the entire grinding process will be divided into two steps, first of all, coarse grinding, followed by fine grinding, then coarse grinding and fine grinding refers to what kind of grinding method, the next for you to do a simple interpretation.

Coarse grinding refers to the material itself because of its own particle size is large, the need to first refine the material itself large particle size and reduce the size of the processing, in this process, the first will use a larger size of the grinding media on the material to carry out a coarse grinding, this process, the grinding time is not as long as the time of fine grinding, but also will not be in the process of quickly reaching a very small particle size, which plays a role in grinding the material particles to the state of the depth of the fine grinding can be continued.

Fine grinding refers to, after the end of coarse grinding, continue to use smaller grinding media, the material will be put into the fine grinding tank, the use of sand mills to the depth of the material grinding process, the end of the fine grinding will be the material to achieve a predetermined grinding particle size of the time, the fine grinding of the size of the discharge particle size is also the final size of the entire grinding of the discharge particle size to be achieved.

After the completion of fine grinding also need to distribute the material particle size detection, in order to determine the overall performance of the sand mill itself, and to determine the uniformity of the particle size in the grinding and the degree of refinement, grinding of the narrower particle size distribution and finer particle size is usually an important factor in judging the overall performance of the sand mill.
