Abstract
An apparatus for sorting pieces of waste of materials having different properties comprises a disk revolving about a substantially vertical axis and comprising a conically upwardly and outwardly tapering rim defining a conveying path, which is concave in cross section, the rim constituting an outer guide wall, and a feeding device for feeding successive pieces to the revolving conveying path at a feeding station. The revolution of the conveying path generates a centrifugal force holding the pieces against the outer guide wall, and a sensor device is arranged along the conveying path for sensing the different properties of the successive pieces. Devices controlled by the sensor device remove single pieces at discharge stations dependent on the sensed properties of the pieces.
