Rotary kiln

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.

Rotary Kilns are commonly used for heat processing of minerals and aggregates such as lime, cement, and iron ore. To achieve consistent quality results, it is important to maintain a uniform product temperature at the kiln entry, mid zone, and discharge. In most rotary kilns, the challenge with temperature process control is that the temperature sensor must view through flames or heavy smoke and dust. Consequently, when selecting a sensor, the design, wavelength, and alignment are all important considerations.

Application fields:Rotary kiln is the equipment which is widely used for dealing with solid material mechanically, physically and chemically in building material, metallurgy, chemical, engineering and environment.

Type of Rotary kiln：Clinker rotary kiln、Limestone rotary kiln、Cement rotary kiln、metallurgy kiln etc.

Clinker rotary kiln：Cement clinker Rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and fuel device.

Limestone rotary kiln：It has the simple structure and reliable operation, at the same the production process of the lime rotary kiln can be controlled easily. Limestone rotary kiln is composed of the shell, the supporting device, the supporting device with thrust roller, the driving device, the movable kiln head, the sealing device at kiln tail, the combustion device, etc. Lime rotary kiln is the main equipment for calcining cement clinker and it can be used widely for cement industry, metallurgy industry, chemical industry, etc.

Limestone rotary kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.

Cement rotary kiln ：Cement rotary kiln are used for the pyroprocessing stage of manufacture of Portland and other types 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 define the capacity of the cement plant. As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of their efficiency has been the central concern of cement manufacturing technology.
