Glass Production

Dolomite and limestone are the third major components in glass raw materials except silica sand and soda powder. Soda powder is the most expensive component in the production of bottle glass. Limestone can replace soda powder in part, but it will have adverse effects. The cost can be further reduced by introducing magnesium oxide in dolomite. Dolomite can also provide calcium oxide in glass industry, and it can be used as a flux by adding soda ash silica system. In addition, dolomite can reduce glass aging, prevent chemical erosion caused by atmosphere or water, improve plasticity of colored glass and improve glass strength.MSdUltrafine Grinder, Ultrafine Mill For Sale

The glass can reduce the viscosity at high temperature and improve the chemical stability and mechanical strength of the products by adding a certain amount of dolomite powder to the glass. The practice also shows that dolomite powder can be used to make low temperature ceramics and float glass ingredients, which can save energy consumption and obtain good social and economic benefits. The quality requirements of dolomite for glass and ceramics are as follows: MgO ≥ 19%, Cao ≥ 26%, Al2O3 < 1%, Fe2O3 < 0.2%.MSdUltrafine Grinder, Ultrafine Mill For Sale

Production Of Glass Ceramics

The properties of the products are better than natural marble and granite. They are suitable for building materials, chemical corrosion resistant materials or wear-resistant materials for metallurgy and mining industries, which opens an effective way to solve the environmental pollution.MSdUltrafine Grinder, Ultrafine Mill For Sale
