Generally, the rotary kiln is divided into several zones the feed zone pre-tropical zone, the lower transition zone, the upper transition zone, the firing zone, and the discharge zone cooling zone.The refractory bricks used are different because of the different working conditions in each location.
The rotary kiln was introduced in the 1890s. It consists of a large steel cylinder tilted at a slight angle from the horizontal and lined with refractory bricks. These bricks have to withstand the stress induced by the rotation, the abrasion from the mineral granules as well as the high temperatures.
Cement rotary kilns are commonly referred to as the largest piece of rotating equipment in the world. Ranging in diameter from 10 feet to more than 20 feet, they are often many hundreds of feet long. As the kiln rotates on its rollers, material is transported due to the kilns low, gradual slope.
In the case of a direct fired rotary kiln, in which the hot stream of gas flows directly through the interior of the rotary kiln, refractory is usually needed. Arguably one of the most critical components of a direct fired rotary kiln, the refractory is what protects the carbon steel shell from the high temperatures within.

Kilns are commonly supported on three supporting stations. Each supporting station has 2 rollers and 4 bearings. All rollers are mounted on one fabricated bed plate. Tyre rests on rollers which have an angle of about 30 degrees at the center of the kiln. Kiln is lined with refractories bricks of 150-250 mm thickness, depending on the diameter ...
The lime rotary kiln is with advanced structure. Its pre-heater with low-pressure loss can improve preheating effect efficiently. After preheating, the resolution ratio of the lime-stones can reach 2025 when they enter the kiln. Besides, the lime-stones, with fine fraction about 1015mm, can be used directly. 2.Waste Heat be Reused Effectively
