Cooling Fans Cement industry uses large number of cooling fans usually between 5 to 15 in one clinker line based on the kiln capacity. Cooling fans are used to blow cold air to the cooler and to cool the clinker from 1500oC to 100oC.
Cement plants that have 4 and 5 stage preheaters have a significant amount of available energy that can be recovered from the kiln exhaust. Most also have available energy from the hot air produced in the clinker cooler. By installing waste heat boilers in these hot gas streams, steam can be produced and used to power a generator (producing electricity) or to drive a fan (offsetting electricity consumption).
Clinker Cooler. After cement is dried by being put through a rotary kiln and converted to clinker, it needs to be cooled. Cooling tunnels are used to reduce the temperature of the clinker from over 2000°F to a workable 200°F. These tunnels typically use forced draft fans to push the cooled air through the clinker. We have been supplying fans to the cement industry for over 30 years, and can manufacture any fan to …

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. Typically kiln feed used to make cement clinker enters the cooler at 1400°C and cools to about 150°C as it travels to the outlet.

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.
Then, there is the rotary kiln, where the sintering - a chemical-mineralogical process during which the cement clinker is formed - takes place at approx. 1,450 °C. Subsequently, the clinker minerals are "fixed" by the cooling process in the clinker cooler.
Clinker is spread on the grate in a certain thickness after discharging into the grate cooler from the rotary kiln. The clinker progresses through the cooler by moving along the grate and so the direction of the cooling air is at right angles to the direction of the movement of the clinker.
