Tube mill is widely used in cement , silicate products , new building materials, refractory materials, fertilizer, ferrous and non-ferrous metals and glass ceramics and other production industries of all kinds of ores and other grind-able materials dry or wet powder mill. Tube mill has a strong adaptability of materials , continuous production, large crushing ratio , easy to adjust the fineness of grinding characteristics of the product . It can also be produced competent wet production , can also be carried out simultaneously grinding and drying operations . In the past, our ultra-fine grinding technology is not perfect, China is rich in kaolin one country can only be non-metallic mineral ore exports at low prices or roughing exported to overseas , and in order to develop their own , we have to buy expensive technology from abroad, always in a passive position . With the development of technology, our ultra-fine powder technology has shrunk. Non- mineral resources more and more into all walks of life , this ultra-fine technique mill building materials industry is bound to bring a big change. And this change will greatly promote the development of ultra-fine powder processing techniques. In addition, some of our large mining machinery enterprises have to spend a lot of money each year to develop our own powder processing applications and research aspects of the product . Especially in recent years has become the main direction of scientific research institutions and professional development of the company 's . At present, China uses more than medium-sized cement plant tube mill , generally composed by a number of Rod Mill      production line , and with superior performance sorting equipment , so that the finished product fineness of the new ISO standard indicators . How to find an efficient way to increase cement new products to adapt to the required cement market , the industrial production of silicate problems need to be solved . The rapid development of the industrial sector and the development of mineral resources is closely related to the promotion of the development of mineral resources , shortage of resources to solve the problem of mine , an urgent need for high efficiency low energy consumption grinding equipment , grinding equipment as milling in the crowd, its entire mineral resources development and the economy plays an important role.
