1. Introduction and application of Rotary Kiln
The rotary kiln refers to the rotation calcining kiln (known as rotary kiln), belonging to the building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials.
Cement kiln is mainly used for calcining cement clinker, including dry and wet process cement kiln.
Metallurgy chemical kiln is mainly used for lean iron ore magnetized roasting in steel plants of metallurgical industry; chromium and nickel iron ore oxidizing roasting; bauxite roasting in refractory plants and chamotte and aluminum hydroxide roasting in aluminium factory; chrome ore roasting in chemical plant.
Lime kiln (i.e. active lime kiln) is used for roasting active lime and light burned dolomite for steel plants and ferroalloy works.

2. Working principle of Rotary Kiln:
The rotary kiln is made up of gas flow, fuel burning, heat transfer, and material movement etc process. The rotary kiln is to make the fuel fully burning, the heat from which can be effectively pass to materials, so that material can produce series of physical and chemical changes after receiving the heat, finally forming finished product chamotte.
Cement kilns are used for the pyroprocessing stage of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
3. Features of rotary kiln:
The special features of the kiln system are high productivity, low heat consumption, stable clinker quality and high economic efficiency.
