ABSTRACT:
In a method of operating an installation for the agglomeration of a particulate charge of a mineral and combustible material mixture supported on an elongate grid, moving through a treatment path, the position of the point of firing of the charge is determined, this position corresponding to the contact of the local combustion zone of the mixture with the grid and the velocity of displacement of the moving grid being modified to maintain this point of firing at a predetermined position in respect of the path. The installation comprises sampling means for determining the instant at which the temperature of the gas passed through the charge rises, calculating means generating a signal representative of the position of the point of firing, and a comparator unit generating a correction signal for modifying the velocity by comparing the correction signal with a reference signal. This improves the regularity of the firing of minerals to be agglomerated.
