method for the separation of a composite material, for example, milling waste, into two fractions, one of which light, used as fertilizer, and a heavy.mainly composed of shards of glass, and device for implementing the method of separator

摘要

A method for the rapid and virtually complete separation of a composite material, such as ground-up refuse, into two fractions, namely a light, largely biodegradable fraction, usable as fertilizer, and a heavy fraction largely consisting of fragments of glass, comprises the following steps: providing a vibrating sloping surface having an upper edge and a lower edge, gravity-feeding the material to be separated onto the said surface in an intermediate position between the said edges, collecting the light fraction that spills off the upper edge and collecting the heavy fraction that spills off the lower edge.
