摘要:
There is disclosed a method and apparatus for separating stones, fibers and plastics from biodegradable material. In an embodiment, the apparatus comprises: an inclined trough (102) having a feed entry (104) at a top end for receiving the feed material, the inclined trough including a plurality of riffles (410, 412, 414, 416) angled to at least partially hinder and unsettle a flow of the feed material flowing down the inclined trough (102); one or more vibratory motors (128) configured to induce a vibration in the inclined trough (102); one or more blowers (107A, 107B) configured to generate an air flow through overhead air vent nozzles (310) positioned over the inclined trough and directing the air flow to one side of the inclined trough (102); and a material resilience separator for separating the contaminants from the biodegradable materials in the remaining material.
