METHOD AND APPARATUS FOR SEPARATING PLASTICS FROM COMPOST AND OTHER RECYCLABLE MATERIALS

摘要

There is disclosed a method and apparatus for separating plastics from compost material. In an embodiment, the method comprises: providing an inclined trough having a feed entry at a top end and a materials discharge end at a bottom end, the inclined trough including a plurality of riffles positioned substantially perpendicularly to a direction of flow of compost material down the inclined trough; inducing a vibration in the inclined trough to induce a prolonged period of hindered unsettling in the compost material; providing a longitudinal dam to at least one side of the inclined trough; and generating an air flow over a substantial length of the inclined trough perpendicular to the direction of flow of compost material down the inclined trough, thereby to blow plastics separated from the compost material over the longitudinal dam.
