The planetary vacuum ball mill tank is mainly developed to address the problem that materials will be oxidized by oxygen in the air during the grinding process of the planetary ball mill. Through the special sealing design of the grinding tank, it can be evacuated and then filled with inert gas to isolate the material from oxygen, water or other substances in the air that may affect the grinding, thereby avoiding oxidation and reducing contact between the material and other substances that affect the grinding effect.
Various sizes can be customized according to customer needs.
