Extensive Use in Non-Metallic Minerals of Ultrafine Mill

As we all know, the three pillars materials industries of China are non-metallic minerals, metal ore and fuel ore, and the development of non-metallic minerals industry has now become one of the hallmarks of a measure of the level of development of the national scientific and technological progress and industrial. According to statistics, non-metallic mineral values have now more than metal ore in many industrial developed countries, and gradually play an increasingly important role in the whole national economy.
    After nearly a decade of research and development, non-metallic minerals industry has made tremendous development, and it will surpass the value of the use of metal ore. The continued improvement of its deep-processing technology is has narrowed the gap with the industrialized counties, and basically have been able to meet their own quality requirements of the industry and related fields required raw materials. The use of non-metallic minerals mainly depends on the extent of its deep processing, including fine purification and surface modification, and the effective is the premise and guarantee of deep processing. Therefore, the stone flour mill, raymind mill,high pressure suspension grinding mill and hammer crusher, jaw crusher and other crushing plant has been widely used in ultra-fine grinding, and the development of its technology determines the rational development and utilization effect of non-metallic mineral products in some extent.
　The survey and analysis show that, the development and utilization of non-metallic mineral products in China has been had 50 years history, and so far, discovered non-metallic mineral with the economic value are more than 100 kinds with the origin more than 5,000. As an important industrial resource, non-metallic mineral accounted 70% of the total mineral extraction. Most of the non-metallic minerals can be directly used in agriculture, chemical, paper, plastics, rubber and coatings products after crushing and...
