Abstract
An apparatus for the transfer or conveyance of a slurry and the simultaneous densification thereof through the intermediary of vacuum pumping. Specifically, disclosed is an apparatus for the vacuum pumping of a slurry, particularly a zinc-containing slurry utilized in the preparation of zinc anodes for alkaline batteries, which facilitates the transfer of the slurry and the concurrent densification thereof in conjunction with the elimination of any gas bubbles which are entrapped in the slurry. Also disclosed is a method of transferring and simultaneously densifying a slurry while eliminating entrapped gas bubbles therefrom through the intermediary of a vacuum pumping process utilizing the disclosed apparatus.
