Non-metallic mineral powder is an important part of modern new materials, with the development of modern industry, the rapid development of new materials, non-metallic mineral flour milling industry continues to develop and improve. China's non-metallic minerals are widely distributed and complete in varieties. With the development of high and new technology, non-metallic minerals have been widely used in the fields of new materials, paper making, plastics, rubber, coating, building materials, metallurgy and so on.

Dolomite is a carbonate mineral, which is widely used after deep processing, and its fineness is different in different fields. Baiyun primary ore dolomite sand, 6-10 mesh, 10-20 mesh, 20-40 mesh, 40-80 mesh, 80-120 mesh, 10 mesh by dolomite powder, dolomite powder of 140 mesh, 325 mesh, 600 mesh, 1000 mesh, 1600 mesh. The dolomite production equipment mainly uses mechanical crushing, crusher, sand making machine and flour mill, the most used is ultrafine mill . It can produce dolomite powder of 80-2500 granularity.

In the metallurgical industry, 30-120mm dolomite ore granularity is an important raw material for the production of magnesium metal, at the same time, one of the most important raw material is alkaline refractory dolomite, comesnext only magnesite, mainly used for steelmaking converter, open hearth furnace, furnace lining wall, then used for refining thermal equipments and cement kiln etc..

In chemical industry, dolomite can be used to produce magnesium carbonate after processing. At the same time, Baiyun stone after processing can produce Magnesium Sulfate, Magnesium Oxide, and other important chemical raw material of magnesium hydroxide.

In building materials industry, the manufacture of magnesium oxychloride cement is another important use of dolomite. In addition, the calcined dolomite generates caustic dolomite, can also be processed into magnesium hydroxide sulfate and Magnesium Oxide cement cement. At the same time, the processing and utilization of dolomite also involve glass, ceramics and other fields. With the development of modern science and technology, the processing and utilization of dolomite has penetrated into every field of social development and become a kind of mineral resources with great economic value.
