ABSTRACT:
A dry material sorting device for selectively sorting mixtures of granular material comprising component materials such as sand and gold having different specific gravities. The use of a horizontal wind tunnel to sort the materials is described. Use of a prescreening device to segregate particles into separate batches based on particle size prior to blowing of the material in the wind tunnel is disclosed. An alternate mode comprising screening of particles after blowing in the wind tunnel using a dynamic screen having variable aperture sizes therein is also disclosed.
