Structure of rotary kiln Rotary kiln is composed of shell, drive device, support and thrust roller, kiln lining, kiln inlet sealing, head hood and burning device etc. Shell is the heated rotation part, which is welded by high quality carbon steel plate.

Cement manufacturing process in a rotary kiln is such that according to temperature gradient in the kiln and the condition of raw materials inside, the kiln may be divided broadly into three zones. Properties and type of refractories for rotary cement kiln will depend on the conditions they will be exposed to in a particular zone of the kiln ...

Φ×74m Rotary Kiln The cement grinding plant mainly used in crushing and preheating of raw materials, and grinding and packaging of cement. And it is mainly applied to deal with And it .

Inner Structure and Advantages of Cement Kiln As a kind of rotary kiln, cement kiln is mainly used for calcining cement clinker and is the main equipment of the new dry type cement production line.

The major characteristic of NSP technology is the preheating of raw materials which ensures that they are substantially decomposed prior to their mixing and feeding into the rotary kiln. This preheating process greatly enhances the efficiency of calcination and formation of clinker in the rotary kiln and reduces the energy consumption in the production of clinker.

This clinker is then ground into cement. For such a kiln the fuel mix (both coal and waste derived fuel) might be around 30 tonnes per hour (tph) and produce some 20% ashes. This means that 6 tph of ashes are integrated into the 200 tph sintering material.

Rotary kilns are used to heat solids to the point where a required chemical reaction(s) takes place. The rotary kiln is basically a rotating inclined cylinder. Rotary kiln is the main equipment used for calcining the cement clinker. It has many advantages such as simply structure, easy operation, less .

Rotary kiln is large critical mechanical equipment with heavy load and low speed (2 ÷ 6 rpm) in production of cement, metallurgical and chemical industry as well as environmental protection [1].

Cement and Rotary Kiln Cameras. Having a constant view of ongoing operations inside the plant is critical.

Rotary kilns (sometimes called calciners or rotary furnaces) are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reduction. These treatments can be applied to powders, granulates, suspensions and green bodies. A rotary kiln consists of a cylindrical, rotating body mounted between stationary material feed and outlet housings.

In order to produce clinker, rotary kilns are widely used in cement plants. This paper deals with the energy audit analysis of a dry type rotary kiln system working in a cement plant in Turkey.
