Rotary Kiln belongs to building material equipment, according to different materials, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln. Cement kiln is used for making cement clinker and there are dry and wet methods to make cement clinker. Metallurgy chemical kiln is widely used for magnetic roasting of poor iron ore and oxidizing roasting of chrome and nickel in the steel factory; backing high-alumina mine in the refractory material factory; baking chamotte and alumina in the aluminum factory and baking chrome ore and chrome powder in the chemical plant. The Lime Kiln is used for roasting active lime in steel works and ferroalloy plants and light roasting dolomite.
The rotary kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly around its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, the materials gradually move down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter- current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or'firing pipe') which acts like a large burner. The fuel may be gas, oil or pulverized coal.

Cement Rotary Kiln Burner/Gypsum Rotary Kiln technical characteristics: ♦ Kiln body is made of high quality composed of carbon steel or alloy steel plate and automatic welding; ♦ Tyre,Support Roller,Open gear adopts alloy cast steel; ♦ Sliding bearing with large gap not scraping tile bearing; ♦ Transmission device adopts hard tooth surface reducer, flexible diaphragm coupling, dc motor; ♦ Adopts hydraulic gear wheel; ♦ Preheater scales were used respectively to veiw of kiln head, and cylinder pressure tight seal; ♦ A slow drive device.
In the Wet Process, the kiln system is fed with liquid slurry, the water then being evaporated in the kiln.
In the Semi-Wet Process, raw material is prepared as a slurry, but a substantial proportion (50-80%) of the water is mechanically removed, usually by filtration, and the resulting "filter cake" is fed to the kiln system.
In the Dry Process, the kiln system is fed with dry raw meal powder.
In the Semi-Dry Process, a limited amount of water (10-15%) is added to dry raw meal so that it can be nodulised, and the damp nodules are fed to the kiln system.
The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with
modern developments. The raw meal was supplied
at ambient temperature in the form of a slurry.
A wet process kiln may be up to 200m long and 6m in diameter. It has to be long because a lot of water has to be evaporated and the process of heat transfer is not very efficient.
The slurry may contain about 40% water. This takes a lot of energy to evaporate and various developments of the wet process were aimed at reducing the water content of the raw meal. An example of this is the 'filter press' (imagine a musical accordion 10-20 metres long and several metres across) -such adaptions were described as 'semi-wet' processes.
The wet process has survived for over a century because many raw materials are suited to blending as a slurry. Also, for many years, it was technically difficult to get dry powders to blend adequately.
In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the kiln.The dry process is much more thermally efficient than the wet process.
