Pay attention to the factors influencing the grinding effect of grinding media of planetary ball mill

- Apr 23, 2018-

The comminution material of a medium ultrafine grinding mill such as a planetary ball mill is realized by a grinding medium. The mechanical energy is transmitted to the grinding medium through a transmission mechanism, and the materials are crushed by various mechanical forces generated between the mediums. Therefore, the physical and chemical indicators of the grinding media and the application process will directly affect the use of the media mill. In a sense, it is the key to the success of the ultra-fine grinding process.

Planetary ball mill grinding media materials, the relative density of the natural will be very different, from the energy utilization analysis, it seems that the relative density of the medium will have a higher grinding efficiency, the actual is not the case. Until now, the relative density of grinding media commonly used in the industry is in the range of 2.2 to 14 g/cm3. How to select a suitable medium of relative density is generally considered to be related to the choice of medium relative density.
