€¢ means suitable for removing metallic materials from the slag in granules, sorting the slag into two flows of material of different grain size, treating separately the two categories of material in granules, with elimination of the unburnt material and the metals, crushing the part of material with the granules larger in size, combining the two categories of material in granules; removing the further metallic parts remaining in said material; finely grinding the granulated material; wetting the finely sorted material for corrosion of the metallic aluminium and dehydrating and/or drying the finely sorted material for use in the production of concrete.</p> |
