Tianchuang powder low temperature planetary ball mill is a combination of planetary ball mill and air cooling device. The air cooling device applies the principle of air conditioning compression refrigeration, and the cold air circulation quickly takes away the heat generated by grinding. According to the different environmental temperatures, the temperature of the ball milling space can be controlled at 5-65438 05℃, which is mainly used for superfine grinding of materials at low temperature. The invention has the advantages of simple structure, convenient operation, convenient maintenance and low energy consumption.
