Abstract
A mineral agglomeration process in which a layer of mineral on an endless conveyor is passed through a firing zone provided with suction windboxes below the conveyor and connected to a common firing suction duct, and then through a cooling zone in which the product is cooled by air drawn through the layer by suction windboxes connected to a common cooling suction duct. The process is regulated by measuring the temperature of the gases in the common suction duct of the cooling zone and using a signal resulting from a comparison of the measured temperature and a preset temperature to control the flow of gases from the windboxes in the firing zone.
