Is a combination of planetary mill and refrigeration equipment. Most materials will be heated during high-speed grinding due to friction or exothermic reaction, which may lead to changes in physical and chemical properties of materials and produce negative grinding effect. Low temperature planetary ball mill is mainly used in material grinding process which needs strict temperature control.

Air-cooling planetary ball mill has four ball grinding tanks installed on one turntable. When the turntable rotates, the tank axis makes planetary movements and the balls in the tanks grinds and mixes samples in high speed movement. The product can smash and blend various products of different materials and granularity with dry or wet methods. Minimum granularity of ground powder can be as small as 0.1mm.
Air-cooling (Low-temperature control) planetary ball mill is a combination of planetary mill and air-cooling device. Air-conditioning compressed refrigeration principle is applied in the air-cooling device. The heat generated by grinding can be quickly removed by air cooling gas cycle. According to the difference of ambient temperature, temperature of ball-milling space can be controlled within 5-15℃. This kind of ball mill is mainly used for ultra-fine grinding under material requirements of low-temperature technology. The air-cooling device has advantages of simple structure, convenient operation, convenient maintenance and lower energy consumption.
1. Suitable for the materials requiring ultra-fine grinding under low temperature.
2. Simple structure.
3. Easy operation.
4. Convenient maintenance.
5. Low energy consumption.
Applications of Air-cooling Planetary Ball Mill
