ABSTRACT:
Lead battery components such as metallic grids and paste are fed into a tumbling drum which has inlet and outlet ends and an intermediate region in which there are screens for the fine particles of paste to discharge to the exterior of the drum. Water is sprayed onto the plates in the drum. A shroud or housing surrounds the region of the drum containing the screens. Means are provided to create subatmospheric air pressure in the shroud and, consequently, in the drum. The slurry of paste particles is collected in a tank which is integral with the bottom of the shroud. The slurry is passed through a cyclone separator and the water extracted by the separator is recirculated through the lines which supply the spray nozzles. All openings in the drum are subjected to subatmospheric pressure.
