Installation for feeding a plurality of loads/cells of aluminum melting furnaces with bulk material such as aluminum oxide

An Installation for feeding a plurality of loads, e.g., cells of an aluminum melting furnace with bulk material, the bulk material including pulverized aluminum oxide, said installation comprising:

• a silo (10) for storing the bulk material;
• a pressure vessel or pump delivering machinery (14) coupled to the silo;
• a conveying line (16) coupled to the pressure vessel;
• a plurality of receiving vessels (26) coupled to the conveying line and disposed proximate the loads (34, 36), said receiving vessels being connected with the conveying line (16) via valves (40);
• and
• at least one pneumatic conveying chute or pneumatic pipe channel (28,30), respectively, connecting a receiving vessel (26) with a plurality of loads (50, 52) of the furnaces (34, 36), said conveying chute or pipe channel (28, 30), respectively, further including at least one discharge (38) per load (50, 52).
