In a method of manufacturing positive tube plates for accumulators a mixture containing essentially Pb and Pb compounds is filled into the tubes of the tubular pockets, which contain a lead core connected to the terminal strip, from the ends of the tubes remote from the terminal strip, until the tubes are full, whereupon the filling openings of the tubes are closed. In this method lead dust is granulated in a granulator (12) with the addition of H2SO4 and H2O in the form of diluted sulphuric acid, and with oxygen being supplied. The still moist granulate (14) is subjected to post oxidation and to size classification matched to the filling chambers in the tubular pockets. The tubes are then filled with the post- oxidised, classified and still moist fine granulate (14') which forms the mixture (Fig. 2). <IMAGE> |
