Rotary kiln is refer to rotate calcination kiln, belongs to construction material equipment. Rotary kiln 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 calcination, which is used for calcining of high aluminum vandal ochre in refractory material industry; for calcining of calotte and aluminum hydroxide in aluminum manufacturer; for calcining of chrome sand ore and chrome powder ore in chemical plant. Limestone rotary kiln are used for calcine dolomite and active lime which is used in steel plant and ferroalloy factory.
In the building materials, metallurgy, chemical industry, environmental protection and many other industries, rotary kilns are widespread used to do physical or chemical treatment of solid material,.
In building materials industry, the rotary kiln used to calcine cement clinker, and also calcine clay, limestone, and dry slag.
In the metallurgical industry, nonferrous and ferrous metallurgy, iron, aluminum, copper, zinc, tin, nickel, tungsten, chromium, filing and other metal use rotary kilns for the smelting equipment, to sinter, roast the ore, concentrates, intermediate, etc.
In the chemical industry, the rotary kiln is used to produce soda, calcined phosphate, and barium sulfide.
In the environment, the world’s developed countries has used cement kilns to burn hazardous waste, waste for more than 20 years, which not only reduce waste, harmless, and slso can use waste as fuel to save coal, so that recycling the waste.
