Abstract:
1. A sorting device for sorting granulated mass containing varied materials, wherein the sorting device comprises a planar, elongated trough conveyor having at least a first elongated and vertical edge; a feeding device for feeding mass into the first end of the trough conveyor; a vibrator provided with a motor and an eccentric, whose rotation axis is disposed in a plane deviating from the plane defined by the trough conveyor so that the mass proceeds obliquely forwards in the trough conveyor towards the first edge and second end; a first suction device for removing the lightest surface portion of the mass near the edge; a guide which is oblique with respect to the edge for bringing apart the mass flow from the edge; and a mechanical separator member for dividing the mass flow into two parts, wherein the mechanical separator includes a wall which directs the heaviest portion of the mass from the direct vicinity of the oblique guide so as to be separate from the rest of the mass, and the mechanical separator includes an adjustment for adjusting the relative amount of the mass to be separated.
