<p>A process is described for producing calcined metal compounds in a rotary tube furnace having downstream modules, where the process is distinguished in particular by it allowing the introduction into the furnace of contaminated or uncontaminated solid-grain, variable feed stock and solid, liquid or gaseous fuel by means of an injection lance, by both fine and coarse calcination products being obtained in desired proportions by targeted process control and at a short calcination time, and a partial circuit procedure which saves resources and energy being possible.</p> |
