Reciprocating type grate coolers can also be used to cool the clinker. The cooling air is used as secondary combustion air for the kiln to improve efficiency since the cooling air has been preheated during the process of cooling the clinker. After cooling, the clinker can be stored in the clinker dome, silos, bins, or outside in storage piles.
