Abstract

"PROCEDURE AND ITS CORRESPONDING INSTALLATION FOR THE MANUFACTURE OF CEMENT BY DRY WAY", according to which the raw materials are heated in a preheater by means of the shafts of a rotary tube furnace and, eventually, of a calcination chamber and then introduced into said furnace, and the clinker produced is cooled at the furnace outlet by means of fresh air which is subsequently used as secondary air in said furnace and, eventually, in the calcination chamber, characterized by the process by using sensible heat of a fraction of the cooling air, which is taken from the clinker cooler at a temperature of the order of 900 to 1000ºC, to calcine, at least partially, a fraction of the raw materials that is subsequently introduced into the oven while, at least part of this air is returned to the refrigerator.
