Apparatus for separating heavier, undesired components from recycle material that includes used aluminum beverage cans. The apparatus includes a particle separation conduit that is positioned between a shredder, for reducing the recycle material to particulate form, and a suction blower, for conveying the shredded material from the shredder into the particle separation conduit and for conveying the separated shredded aluminum alloy to a receptacle after separation of the heavier components, which can include lead, brass and glass. Adjacent the conduit inlet is a diverging first section that has a gradually enlarging cross-sectional area, and adjacent the conduit outlet is a significantly shorter length, second section that has a decreasing cross-sectional area. The first and second sections are joined in a region close to the conduit outlet. A second outlet opening is provided in the lowermost portion of the conduit at the junction of the first and second sections to permit the withdrawal of heavier, undesired particles from a flowing air stream containing shredded recycle material.
