<p>Apparatus for sorting and recovery of scrap material, particularly aluminum beverage can scrap, includes a rotary kiln (10) in which the raw scrap is heat processed to leave a furnace chamber (12) of the kiln as a mix of large particles of a first composition (e.g. larger pieces of soft aluminium alloy can body) and substantially smaller particles of a second and different composition (e.g. aluminium/manganese alloy can top fines). The output end of the kiln is provided with an axially extending screen section (30) to separate the larger particles from the small immediately adjacent to the chamber so that they cn be passed immediately without substantial loss of heat to a melting furnace (38).</p> |
