Recycling Sand from Foundry Casting Molds

    The flowsheet shown in this study is particularly adapted to the requirements of the average foundry to reclaim foundry sand for re-use. Any foundry whose new sand delivered costs is too high should seriously consider reclamation with the flowsheet as illustrated. This reclaimed sand is usually equal to, or better than the original sand.
