Rotary Kiln Introduction：
Rotary kiln refers to rotating calcination kiln, belongs to construction material equipment. According to the different materials, the kiln can be divided into cement kiln, metallurgy chemical kiln and lime kiln. The cement kiln is mainly used for the calcinations of cement clinker, and it has two types of dry and wet methods. And the metallurgy chemical kiln is mainly applied in metallurgy industries, like, magnetizing roast of the poor iron ore in ironworks, oxidizing roast of the chromium and nickel ore, roast of the high aluminum bauxite in refractory material industry, roast of clinker and aluminum hydroxide in aluminum manufacturer, and roast of the chromium ore and chromium powder in chemical industry. The lime kiln is mainly used for roasting the active lime and light roasting of the dolomite in ironworks and ferroalloy works.
