FIELD: electrolysis of aluminium. SUBSTANCE: gear feeding powdery starting material, for instance aluminum oxide, into electrolyzer in process of electrolysis production of aluminum has supplying and feeding means manufactured in the form of bin with pipe-line, batcher, vibrator with driving aids to create mechanical vibrations and feeding unit made in the form of feeding tube, feeding member snugly placed in tube and linked to vibrator to create vertical vibrations with the help of piston shaft. Regulation box with open part positioned in zone of location of surface of molten electrolyte for operation in crust of the latter is connected to feeding tube. EFFECT: improved efficiency and reliability of gear. 7 cl, 4 dwg
