The cryogenic planetary ball mill is primarily designed for applications involving special materials that must not generate any heat during the grinding process. Certain products require grinding under specific temperature conditions. Our cryogenic planetary ball mill addresses this issue. For the cryogenic planetary ball mill, we offer two processing approaches. One involves the use of liquid nitrogen to directly lower the temperature. While this method can maintain a relatively low temperature, the duration of operation for liquid nitrogen-based cryogenic ball milling is limited. The other method is the cryogenic system, which can sustain a certain lowered temperature for a longer duration but doesn’t achieve the ultra-low temperatures of the liquid nitrogen approach.
