· The clinker cooler is an essential element in the production of cement. The cooler, as the name implies, cools the clinker to manageable levels while transporting it away from the kiln. It also recovers heat from the clinker for use in the kiln, precalciner and other areas. In addition, the cooler sizes the clinker, breaking up large pieces.

In fact to transform the raw meal into clinker, the temperature needs to be as high as 1450°C (2642°F). As the name implies, the clinker cooler lowers the temperature and carries the clinker from the kiln. It also provides heated air for the rotary kiln and the preheater. The clinker is cooled to a temperature of about 150°C (302°F).

In this base case, the clinker residence time in the cooler is 20.9 min and the clinker-discharge temperature 224 F. Now assume that the kiln suddenly starts to discharge clinker at a rate of 89 tons/h and that the grate speed is on automatic control, i.e., starts to increase the speed to maintain the same clinker-bed depth (see Table 18.2).

· Definition of Clinker. Clinker is a hard, black, or dark grey substance created when coal is burned. It’s made of ash, soot, and minerals that fuse together at high temperatures. Clinkers can form on the fire grate, inside combustion chambers, or in flue pipes. These lumps can damage furnace components and reduce efficiency if not removed.

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.
