<p>A sorting method and apparatus is provided in which a flow of particles or objects to be sorted is accelerated by being caused to descend an inclined chute (12) after which the stream or streams discharged from the chute are scanned transversely from one or both sides and while in free fall by one or several linescan cameras (14). The chute may be arranged to divide the flow into separate side by side streams. In a particular arrangement, two cameras scan the streams successively at respective different levels. The linescan data captured by the cameras is then processed to derive signals for operating downstream sorting means (17).</p> |
