Planetary ball mills are the best in ultra-fine ball mills, not only because of their high performance, but also because of the wide range of applications of planetary ball mills. There are countless materials that can be ground with a planetary ball mill, and the characteristics of the materials are all sorts of strange. Grinding different materials in the same way will get different results, so to control the particle size of planetary ball mills, we must start from many aspects.
The planetary ball mill is the simplest and most direct method to control the grinding particle size and change the grinding time and rotation speed, but it does not mean that the higher the rotation speed, the better, the longer the grinding time, the finer the grinding. The variability of materials cannot be generalized. The optimal speed and grinding time need to be continuously verified by experiments and actual usage.
The type, size, ball loading rate, ball-to-material ratio, etc. of the grinding balls will affect the particle size of the planetary ball mill. Generally speaking, the finer the material, the smaller the grinding ball is selected. The large ball is mainly used for preliminary crushing. Material characteristics to match the ratio of the big and small balls.
The planetary ball mill supports both dry and wet grinding, but wet grinding is higher in efficiency and particle size than dry grinding. In the grinding process, the addition of grinding aids or dispersants reduces the agglomeration and re-fusion of materials; the amount of grinding aids and dispersants should also be paid attention to. The finer the particle size of the ball mill powder, the larger the surface area, and the adsorbed agent If it increases, more will be added.
