The YD-XQM Series Liquid Nitrogen Cooling Planetary Ball Mill is a specialized device capable of ultra-fine grinding at ultra-low temperatures between -60°C and -1°C. An integrated liquid nitrogen tank with a level/temperature controller feeds the chamber automatically.

Key Features

Liquid level/temperature controller on the nitrogen tank — automatic temperature control and reduced nitrogen consumption.
Chamber temperature adjustable from -60°C to -1°C for ultra-fine grinding at ultra-low temperature.
Patented silent oil-seal design — 50% lower noise and 2x longer service life.
Power is automatically cut when the lid is opened, preventing the jar from flying out of the machine.
