Rotary kiln furnace design handbook. A rotary furnace is a barrel-shaped instrument that is rotated around its axis when performing heat treatment. These instruments are tilted slightly to allow the sample under This sample transfer occurs as the rotary furnace rotates, and this rotation can also induce some mixing or stirring of the sample.

The cylinder of the rotary kiln's main structure is the kiln shell, rim, and thrust roller. Shell is the main part of the rotary kiln. It is a steel plate with a 40mm thickness, which is near the rim. Because of the high load-bearing, the thickness near here is much thicker. There is a layer of 200mm refractory bricks on the inside of the kiln.

The length of each part of a rotary kiln is designed based on the inner diameter (D) of the kiln shell. 1) The length of the kiln head overhanging section (l1): l1= (1.2~1.5) D. As the first section of a rotary kiln, l 1 is better not to be designed too long, or the length of the effective parts of the kiln will have to be shortened.

For these most common rotary kiln materials, high temperatures in the range of 1100°C / 2000°F are used to instigate a chemical conversion (cement and lime) or to fuse fines (fine ore powder) into pellet form (iron ore). Most rotary kilns are direct fired – with a flame shooting into the kiln from the discharge end (the fire wall).

Rotary driers have thermal efficiencies of from 50 to 75 per cent on ores. This must be taken into account when using the above table, which is figured at 100 per cent. The drier shell is rotated separately from the stationary kiln section. To achieve the rotation a BULL GEAR is attached around the shell section.

the rotary kiln. Direct-fired rotary kilns can operate in either the co-current mode, where combustion gases and solids move in the same direction, or in the counter current mode, where the gases and solids move in opposition to each other. While all FEECO kilns are custom engineered around the material to be processed and the unique processing
