Patent ID: 8850831

Claim:
Method of cooling granular materials coming from a continuous curing facility ( 1 ), having at least one area for burning ( 41 , 42 ) a fuel for the curing of the granular materials, wherein is carried out the curing of the granular materials in said facility then the cooling of said cured granular materials in two consecutive steps, a first cooling step implemented in a first cooler ( 2 ) of the facility and a second cooling step implemented in a second cooler ( 3 ) of the facility, method wherein: a cold air source ( 31 ) is provided for the cooling of the granular materials, said cold air source ( 31 ) supplying directly said second cooler ( 3 ) by air blowing, the air heated by the cured granular materials, during the cooling, is used as combustion gas for said at least one area for burning ( 41 , 42 ) of the facility ( 1 ),characterized in that: the totality of the gases ( 133 , 134 ; 222 , 234 ; 334 , 335 ) generated by said first cooler ( 2 ) and said second cooler ( 3 ) are routed towards said at least one area for burning ( 41 , 42 ) of said curing facility in order to be used as combustion gas, without filtration of said gases, the quantity of cold air ( 31 ) blown to said second cooler ( 3 ) is adjusted in such a way as to cover but not excessively the air combustion needs of said facility ( 1 ).
