Cement Kilns: Clinker Coolers

Coolers are essential parts of rotary kiln systems Clinker leaves the kiln at 1200C or more Clinker at this temperature has a heat content of 1 22 MJ/kg and must be cooled in order to: avoid wasting this heat energy obtain clinker at a temperature suitable for grinding - less than 100CGet price


Effects of grate cooler dynamics on cement process simulation

The cement clinker leaving the kiln consists of hard granular particles ranging from 1/8 inch to several inches in diameter This clinker is transported through a cooler (Figure 1) on a moving grate while a controlled stream of air passes through the bed of clinker The heated air from the cooler is then used for burning the fuel in the kiln Get price
