At present, China has become the world's coal, iron and steel, iron ore, alumina, copper, cement consumption of the largest country, is the world's energy consumption of second major countries.

According to statistics, the power consumption of the ball mill in the mine is about 40%-50%, the power consumption of ball mill in the cement industry can reach 70% of the total power consumption, the power consumption of ball mill in the thermal power industry accounts for 30% of the total electricity consumption of the whole country. With the lack of high quality coal, ore and other resources, industrial production in a large number of poor use of material makes the crushing efficiency of the ball mill is generally reduced, so that the energy consumption per unit output further increase.

Today, our country insists on the road of sustainable development of "reduction, reuse, resource". Taking the government as the leading, enterprise as the main body, the whole society to participate in the energy conservation and emission reduction work pattern, is gradually forming in our country. That is to say, "energy saving" is not only an urgent need for the development of enterprises, but also related to the people's livelihood. With the development of the technology of ball milling, the environmental protection and economy of ball mill are getting more and more attention. Therefore, only to continue to strengthen energy conservation and innovation, to achieve the long-term development of ball milling.
