Table 1 presents the design parameters used.
In the design of kilns, there are four important aspects to consider from a process engineering point of view, and these are heat transfer, flow of material through the rotary kiln, gas-solid mass transfer and reaction.
The basic components of a rotary kiln are the shell, the refractory lining, support tyres (riding rings) and rollers, drive gear and internal heat exchangers. History The rotary kiln was invented in 1873 by the Englishman Frederick Ransome .
Because of demonstrated performance benefits,rotary kilns utilize forgings for rollers and shafts,as well as for tires. Forged from 1045 steel, the "riding tires" for rotary kilns outperformed cast A27 steel and usually cost less as a final product.

Rotary kiln body, with drive gear and 2 tyres (riding rings) A rotary kiln is a pyroprocessing device used to raise materials to a high temperature ( calcination ) in a continuous process. Materials produced using rotary kilns include:
Higher SO 2 emissions by rotary kiln systems in the cement industry are often attributable to the sulfides contained in the raw material, which become oxidised to form SO 2 at the temperatures between 370 °C and 420 °C prevailing in the kiln preheater.
4 Due to the interaction of raw materials and kiln gases, rotary kiln systems have inherent SO2 removal efficiencies ranging between 40-99% of the sulfur input to the system. The literature suggests that 50-70% of the remaining SO2 will be removed from exhaust gases when passed through an in-line raw mill system.
