<p>RECOVERY OF ALUMINUM FROM ALUMINUM-GLASS CLOTH RESIDUES A method is described for reclaiming aluminum from aluminum-glass cloth residues in which the glass cloth fibers are coated with aluminum, the glass cloths having been used for the filtering of molten aluminum. The method comprises the steps of: breaking down the residue into small pieces by the action of a rotating multi-blade cutter in cooperation with at least one fixed blade and a contoured screen whereby the residue is continuously chopped until pieces thereof are fine enough to pass through the screen. This chopping action effectively frees the glass fibers from the aluminum and the resulting freed glass fiber is then separated from the remaining aluminum pieces by air separation. The recovered aluminum pieces can be then reused in various industrial processes.</p> |
