contact usCoolers 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.
contact usThe rotary cooler is of simple design and is the oldest type of clinker coolers. It was seldom used for modern large kiln systems. Therefore comparatively little design and operating experience is nowadays available for rotary coolers above 2000 t/d. However the application of rotary coolers still offers certain advantages.

contact usCoolers are essential parts of rotary kiln systems. Clinker leaves the kiln at 1200°C or more. Clinker at this temperature has a heat content of 1.22 MJ/kg and must be cooled in order to: avoid wasting this heat energy; obtain clinker at a temperature suitable for grinding - less than 100°C
contact usIn modern clinker coolers, the cooling air passes through the clinker at right angles, whereby the air absorbs the thermal energy. Via the kiln hood, this recuperated heat is passed to the rotary kiln as secondary air, or as tertiary air via the tertiary air duct. The clinker is then transported to the breaker via pusher grates, fixtures, or ...
