Abstract
A machine for sorting recyclable matter includes a trommel for conducting and screening an input flow of recyclable matter and a magnetic mechanism coupled to the trommel for extracting magnetic material from the input flow while the trommel rotates. The input flow is dropped vertically from the trommel into a positive-pressure air separator which separates the flow into a first material stream including lightweight articles and a second material stream including relatively heavy articles. The heavy articles of the second material stream drop downwardly in the air separator. Padded baffles are provided in the air separator for reducing the downward velocity of the second material stream, which substantially lowers breakage of glass articles.
