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 essential design elements of a rotary kiln are shown in Fig 1 and Fig 2. The rotary kiln consists of a lined hollow cylinder, mounted in an inclined position on rolls and rotated slowly by a drive. The charge material moves from the feed end to the discharge end as a result of the rotary motion and gravity.

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.
