Rotary kiln belongs to building material equipment, which 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 for magnetic roasting of iron ore and oxidizing roasting of chrome and nickel in the steel factory; baking high-alumina mine in the refractory material factory; baking chamotte and alumina in the aluminium factory and baking chrome ore and chrome powder in the chemical plant. Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.

Rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and combustion. Cylinder as heated pivoting part, made of high quality carbon steel plate, is supported on the support device by tire, and there is mechanical or hydraulic pressure catch wheel on the first or some gear in order to control the turning of cylinder. Because of the need of installation or maintenance, the bigger rotary kiln has auxiliary gears, which makes cylinder gyrate more slowly. To prevent cold air come in and dust overflow, the reliable kiln tail and head sealing equipment is installed on feed and discharge end.

Rotary kiln is the main equipment of coalmining the cement clinker. The characteristics of a rotary kiln are with simple structure, convenient and reliable control of the producing process, with little wearing parts and high running rate. It is the equipment coalmining the high grad cement in the cement factory. The rotary kiln is widely used in the metallurgy, chemical industry, construction and other industries.
