With the development of economic, the exploitation value of the metal mineral and non-metallic mineral has increased day by day. According to related statistics, the trend of development of the non-metallic mineral raw materials in the future is high purity and ultra-fine. Although it is possible to prepare the ultrafine powder by chemical synthesis, but the cost is too high, so it failed for the industrial production.

　　Currently, according to the product particle size, the crushing and processing of the non-metallic minerals is divided into three levels, they are crushing (product size 35mm-1mm), grinding (product size 1000um-10um), and ultrafine grinding or fine grinding (product size 10um-0.01um). According to statistics, using grinding mill equipment to grind the ore is still the main means processing the metal mineral and non-metallic into superfine powder.

　　Great Wall Machinery adopted top technology of domestic and abroad, and based on many years’ mill experience to design and develop the advanced mill. The mill of our company can be widely used in such industries as cement, electric power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and materials into powders with required fineness.
