2018123ing bars fitted above the stationary air distribution system effectively convey mix and shear the clinker while at the same time preparing the clinker for efficient exposure to the cooling air. A further benefit to this separation is that gradual wear of the bars has no effect on cooler operation and thermal efficiency stays high.
Materials
The clinker discharged from the rotary kiln enters the rotary cooler and is rapidly quenched with water from 1400C to 600C. The clinker subsequently passes through the roll crusher which produces grain sies 50 mm. Finish cooling from 600C to the ultimate temperature of approx. 100C is performed on the vibrating grate with air.

High maintenance costs are also associated with conventional cement cooling technologies as regular maintenance is required to prevent caked and solidified material build up inside and outside the tower. Lastly there is a negative environmental impact on air emissions from the dusty mill house and contaminated water from the cooling process.
