Technology value and use of equipment for powder processing of mineral raw materials
With economic development,the development and utilization of metal and non-metallic mine increased. According to related statistics, in the future, non-metallic mineral raw materials or materials' overall trend is high purity, ultra-fine and functional. High purity ultrafine metallic mineral processing raw materials as the leading, comprehensive develop and utilize a variety of non-metallic minerals. Although prepared by chemical synthesis purity ultrafine powder, but the cost is too high, so failed for industrial production.
Currently,according to the product particle size, non-metallic minerals crushing process can be divided into: Shattered (product size 35-1mm), grinding or milling (product size 1000-10um) and ultrafine grinding or fine grinding (product size 10 - .01 um) 3 levels.
According to statistics, non-metallic mineral processing superfine powder metal mines are still the main means of mechanical grinding methods, that is, using mill equipment for ore crushing. However, using mechanical means to obtain fine powder of ultra-fine grinding and classification depends technical difficulty is increasing, and the depth of its research endless.
