Rotary kiln drives the cylinder body to rotate through transmission device and continues to be heated at high temperature to meet the heat transfer requirements of each stage of the clinker formation process and the requirements of heat, temperature and time for the formation of different minerals as well as physical and chemical reactions. The kiln body is composed of refractory bricks, castables and special steel cylinder body. Used in building material, metallurgy, chemical and environmental protection industries, for calcining cement, active lime; for nickel, iron, lithium, chromium and other non-ferrous minerals oxidation roasting and gold copper smelting; for calcining calcium carbonate, titanium dioxide, magnesium oxide, zinc oxide, coal oil; for coal clean dry distillation, coal eff
