A rotary kiln consists mainly of a long inclined rotating cylinder which is usually driven by a direct current motor (Fig. 1). The material to be treated is continuously fed into the upper end of the cylinder and transported to the discharge end due to the inclination and rotation of the cylinder, being dried or calcinated in high temperature ...

Analysis of Heat balance was used to determine the sources of heat loss from the kiln system. Based on the collected data, an energy balance is applied to the kiln system. The physical properties and equations can be found in Perry's handbook. The reference enthalpy is considered to be zero at 0°C for the calculations.

Another key reason rotary kilns are chosen is their high capacity. A direct-fired kiln can process anywhere from 1 to 25 tph (0.5 to 22 metric tph) of material, while indirect-fired kilns can process between 200 lb/h to 20 tph, making them an ideal option for high-capacity settings such as mineral processing and the production of roofing granules.

A heat balance, simply stated, consists of compiling all the heat that is given to the kiln and then comparing this total to the total of thermal work done and heat losses that occur in the system. Whatever heat put into the kiln (INPUT) must be accounted for in one way or another by the heat that goes out of the system (OUTPUT).

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.
