I plant the production of light burned magnesium oxide using the most high-quality magnesite, after crushing, screening appropriate particle size is added gas reflection kiln (900-1200 ℃), calcined kiln kiln temperature control system is arranged by kiln temperature to Strict control activity and the content of magnesium oxide. Can greatly improve the quality and stability of the finished product, less impurities. To ensure the quality of our semi-finished products through rigorous manual screening, the burnt product and under-firing product selection screening. Semi-finished products retain the content of Raymond just pulverized.
