Abstract (en)
[origin: EP0247423A2] The object is to simplify a method in which the material is possibly reduced in size, dried and then separated into fractions. This is achieved by subjecting the material on an essentially flat, sloping screening tray (3) to vibration which produces a component (27) of movement for the material which is essentially opposed to the slope (8), by subjecting the material to a stream of air (29) which crosses the screening tray (3) in an upwards direction and reduces the contact between the material particles and the screening tray (3) and removing the fractions at outlet points (11 to 14) arranged along a line (5) which includes an open acute angle (w) with the direction of conveyance (27) and opposed to the latter. The invention also relates to a device for carrying out the method. <IMAGE>
