Operation principle of the clinker cooler Stationary, low-wear aeration grate. The air is distributed to the material bed via static aeration units located between the transport tracks. Since the aeration plates do not move and the conveying elements are sealed with a continuous sealing from the adjacent aeration floor, there is virtually no

Clinker enters from one end and is lifted and scattered by flights. At the same time, the cold air enters from the other end and contacts with the clinker countercurrent for heat exchange. The rotary cooler is generally arranged under the rotary kiln, with a diameter of 2-5m and a length of 20-50m. Grate cooler Grate cooler is a quench type cooler.

Clinker Coolers August 20, 2022 In cement manufacturing, formation of clinker nodules occurs at the entrance to the hottest part of the kiln with a material temperature of around 1280°C. The clinker is preferably in the form of 10-mm to 25-mm size nodules that exit from the front end of the kiln into the cooler.

Typically, the clinker coolers release large amounts of heated air at 250 to 340° C which can effectively be used in WHRS system. The steam turbine based waste heat recovery boilers (WHRB) are placed between the cooler and the de-dusting system. Depending on situations / requirements, various configurations are considered which are shown below.
