Abstract

Procedure for hard calcination of mineral nodules, raw materials for cement and the like on the sintering belt with drying of the green nodules in a pre-drying zone with the hot gases, returned from the following zone, upwards through of the load and of a subsequent drying zone with passage of the hot drying gases downstream through the load; with heating of the nodules by using the hot gases from the first of the two cooling zones and circulating through the load in the downward direction; calcination in a main calcination zone using hot gases from the first of the two cooling zones and circulating through the load in a downward direction; post-calcification in a post-calcination zone not provided with burners with hot gases passing downwards through charging and cooling under pressure in two areas of the calcined nodules, with upward air flow through the load, characterized by that the air of the first cooling zone after passing through the load without intermediate use of a fan is taken directly to the heating, main calcination and postcalcination zones, being used there as secondary air and in such a way that at least the part of this Air that has passed through from top to bottom the load of the postcalcining zone after leaving it, is driven through the load in the first drying zone in an upward direction.
