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.
