Abstract
Greater uniformity of particle size and free-running properties are achieved in the production of granular material for lead storage battery electrodes by adding water or sulfuric acid to a mixture of granules of lead and lead oxide to produce a paste which is pressed through a foraminous body such as a filter cloth and the resulting granules dried by permitting free fall through a heated gaseous drying medium. Novel apparatus for carrying out the process is also disclosed.
