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.
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 sand ore and chrome powder ore in chemical plant.
Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.
