FIELD: electrolytic production of aluminum, particularly, electrolyzers for production of aluminum with self-baking anodes and top current lead and provided with devices for automatic supply of raw materials. SUBSTANCE: electrolyzer includes anode shell, gas-collecting bell and device for supply of raw material connected with hollow of gas-collecting bell and consisting of bin, valve-type batch box connected with bin, and punch for breakage of electrolyte crust with rod and drive. Punch is located coaxially with respect to bin. Device for supply of raw material is connected with gas-collecting bell through reducing chamber made with tightly closed hatch. Punch for breakage of electrolyte crust has return spring. EFFECT: higher operate reliability of device for supply of raw material, reduced labor input for device servicing and servicing of zone of raw material supply. 5 cl, 5 dwg
