QM-DY20 Cryogenic Planetary ball mill is an essential device for mixing, finely grinding, developing new products and small batch production of high-tech materials. It has small appearnce, complete functions, high efficiency and low noise, and is widely used in pharmaceutical, chemical industry, environmental protection, light industry, building materials, metallurgy, ceramics, mineral and other sectors.

Working principle

The cold air produced by the liquid nitrogen is continuously injected into the ball mill, and absorb the heat generated by the high-speed running of the jars. So the jars filled with materials and grinding balls are always in a low temperature environment.
