Coolers and Kiln Hoods

Coolers receive hot material (clinker) discharged from the kiln and cool it as it is conveyed to handling and storage systems. To cool the clinker, ambient air is blown via fans up through the porous floor of the cooler. The service environment of the cooler is extremely abrasive, subject to wide swings in temperature and alkali attack.

Clinker cooler – level and pressure measurement | VEGA

To produce cement, the raw meal is burned to clinker in a long rotary kiln. After leaving the rotary kiln, the clinker has a temperature of up to +1300 °C and must be cooled down to a temperature of about +200 °C for further storage. To achieve this, the clinker bed is cooled with a continuous stream of air.

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.
