<p>According to the process, the residues to be treated are firstly subjected to a baking process using electromagnetic waves, then to a pneumatic flux in a heated medium to produce an inert material in the form of anhydrite. The plant is characterized in that the residues to be treated are subjected to weighing, fed into an electromagnetic baking furnace (1 to 4), conveyed to a regulating silo fitted with a helicoidal screw (5 to 8), disintegrated and screened (9), carried by a pneumatic flux (10 and 11) into a grinding cylinder with heating rods (12 to 17), then collected in the form of anhydrite powder.</p> |
