Rotary kiln

Rotary kiln is generally called rotary calcining kiln. It belongs to building equipment such as chemical rotary kiln and active lime rotary kiln. According to different materials, there are cement kiln, metallurgy chemical kiln and lime kiln. Cement kiln is widely used for calcining cement clinker and there are two types for cement production: dry cement kiln and wet cement kiln. Metallurgy chemical kiln is used for metallurgy industry, for example, in iron and steel plant for magnetic roasting of depleted iron ore and oxidizing roasting of chromium and nickel iron ore; in refractory plant for roasting high alumina bauxite mine; in aluminum plant for roasting clinker aggregate, aluminum hydroxide; in chemistry plant for roasting chromium ore and similar ores. Lime kiln (lime rotary kiln) is used to roast active lime for steel and iron plant and ferroalloy plant and lightly calcine dolomite. Sawdust Dryer：http://www.ms-machinery.com/product/sawdust-dryer.html

For environmental protection, in the history lasting for 20 years, developed countries have calcined and burnt dangerous waste and garbage with cement kiln which reduces the waste and has no harms, and also it can reuse waste as the fuel so as to save coal powder and achieve waste recycling. Rotary Kiln: http://www.ms-machinery.com/product/rotary-kiln.html
