ABSTRACT:
The sorting method includes moving materials at a certain horizontal speed such that on falling their points of impact are disbursed over a moving sorting belt in such a manner that the materials become located at points which are sufficiently different to enable effective sorting to be obtained by small adhesion differences so that the adhering materials are carried by the sorting belt to a discharge region and the non-adhering or weakly adhering materials are rejected by the belt. The apparatus includes a feed device located above a moving adhesion belt having an adjustable speed control and an arrangement for adjusting the position of the feed device relative to the adhesion sorting belt.
