China's powder industry has become an interdisciplinary industry. The output value of China's powder industry accounts for more than half of the total output value of the first and second industries, and plays an important role in the national economy.

The development of powder industry must rely on grinding equipment. However, no matter how the development of the ultrafine mill industry is now, it can not determine the development of the mill industry in the next few years.

No matter now or in the next few years, the development of the mill is for the better development and future of the mill enterprise. Ultrafine mill is one of the most difficult barriers for the development of the mill industry in the future.
