The planetary ball mill TM series of Lianyungang Chunlong Experimental Instrument Co., Ltd. is a vertical ball mill. Divided into 4, 6 and 8 grinding tanks.
Grinding materials to a certain particle size with a planetary ball mill should pay attention to the use of grinding balls and ball grinding tanks. Generally, the size of the medium to be ground is small, and there are many media ball contacts. In general, the feed size is small, the finer the product size, the smaller the media diameter size.
The shape of the planetary ball mill media is mainly spherical and irregular. The more the media contact type of the planetary ball mill changes, the narrower the grinding particle size distribution.
The contact of the point, line and surface provided by the columnar grinding media produces a much narrower particle size distribution than the spherical grinding media, which produces a product particle size distributed between the sphere and the cylinder. However, in the industry, irregular media tend to be subject to greater wear and tear, causing significant pollution. Spherical media are used in practical applications, and cylindrical media is also used. As for irregular media applications, there are few applications.
Generally, the artificial grinding medium of the planetary ball mill is mostly spherical. When the medium spherical shape is poor, the rotation motion is blocked, which is not conducive to smashing, but the wear is increased.
The grinding medium has poor smoothness, increased wear, and high pollution to the product, that is, damage to the surface where the pores are present, the uneven surface, and the surface of the material. For example, in the production of flaky mica powder, aluminum syrup, and zinc syrup, when selecting a medium ball, special attention should be paid to the shape of the ball and the surface roughness of the medium, because the flaky surface is not expected to have scratches or the like.
