Dolomite Refractory Products In Cement Industry

Why Dolomite? There are a number of unique properties in dolomite brick that make dolomite well suited for use as a refractory lining in a cement rotary kiln. A high degree of refractoriness allows the dolomite brick to withstand the temperatures and stresses involved in the burning zone, the corrosion resistance to alkalis, and a reducing atmosphere, as well as excellent coatability.
