Title: SINGLE STREAM OF AIR FOR SEPARATING MIXED WASTE STREAM INTO THREE FRACTIONS
Abstract:
Separation and classification equipment for separating a mixed waste stream into first, second and third fractions. The equipment comprises a feeding member for feeding the waste stream toward a gap and a blower for discharging a stream of air for mixing with the waste stream, as the waste stream falls through the gap. The first fraction falls through the stream of air and collects in a first collection area while the stream of air carries away the second and the third fractions. A rotatable permeable member is arranged to permit the stream of air to pass therethrough and thereby force and retain the third fraction against a surface of the rotatable permeable member and be conveyed, by the rotatable permeable member, toward a third collection area while the second fraction tends to separate, from the rotatable permeable member and the third fraction, and collect in a separate second collection area.
