Fans in cement industry are heavy duty and perform two basic functions i.e., supply of air or removal of exhaust gases and material handling. There are many process fans that find applications in cement industry such as raw mill fans, induced draft fans, cooling fans, raw mill exhaust fans, coal mill fans and cooler exhaust fans.

Conditioning towers in the cement industry are used for cooling exhaust gases from the kiln before they are conveyed to the bag house. Inlet temperature from pre-heater to Gas Conditioning tower is 600 degree Celsius and outlet is 250 degree Celsius. This temperature is used to drying material in vertical raw mill.

Clay component. The other important raw material for cement manufacture is clay. Clay is formed by the weathering of alkali and alkaline earth containing aluminum sili­cates and of their chemical conversion products, mainly feldspar and mica. The main component of clays is formed by hydrous aluminum silicates.
