Rotary kiln belongs to building material equipment, and it can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials. Hongxing cement rotary kiln is mainly used for calcining cement clinker and it has dry and wet two types. The metallurgy chemical kiln is mainly used for roasting iron ore, chromium and nickel; it can also roast the clinker, aluminium hydroxide and other refractory materials. The cement rotary kiln (active lime kiln) is mainly used for roasting active lime and light-burning dolomite in the steel and ferroalloy works. The cement rotary kiln has firm structure, smooth operation and high quality products. We will also offer advanced preheater, five-class cyclone preheater. The kiln contains cylinder transmission device, bearing device, sealing device, and fuel device. According to different heating methods, the kiln can be divided into internal heating cement kiln and external heating cement kiln. The material can directly contact with flame and flue gas for the internal heating cement kiln. For the external heating kiln, the material does not directly contact with flame and gas; the heat source is between the cylinder and heating furnace, which heat materials in the help of heat-resisting steel tube. The inner line is made of fire-resistant fiber, which can save energy significantly. Not only in the industry but also in the environment protection, the cement kiln has an important role. It can burn hazardous waste to reuse them, which can save energy and improve resource utilization. Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. Metallurgy chemical kiln is used in metallurgy industry and ironworks for lean iron ore, chromium ore and ferronickel ore calcimine. Rotary kiln is used for calcimine of high aluminum vandal ochre in refractory material industry; for calcimine of calotte and aluminum hydroxide in aluminum manufacturer; for claiming of chrome...
