At the same time, however, the ball mill has a low energy utilization rate (less than or equal to 10%), most of the energy is not fully utilized, and the energy is lost in the form of heat mainly through frictional heat generation of the grinding media and the materials. One part of the powder is radiated and lost through a cylinder of the mill, in addition, the temperature of the ground powder is higher and can reach 60-80 ℃, the high-temperature powder is easy to agglomerate and is not beneficial to the subsequent packaging of powder products, and the high-temperature powder is easy to absorb moisture in the packaging process, so that the moisture of the products exceeds the standard. The ball mill has low energy utilization rate and does not conform to the current national policy of energy conservation and consumption reduction. On the other hand, the north of China has cold weather, the heating time is as long as 5 months every year, and the energy demand is large.
