Abstract
A nonferrous material sorting apparatus comprises a screening device for screening nonferrous materials to be sorted into materials of a plurality of size ranges, a first sorting device for sorting the nonferrous materials of the minimum size range according to the weight ratio by an inclined vibrating air table supplied with air, and a second sorting device for sorting the nonferrous materials of the size range larger than the minimum size range according to the size in specific gravity of the nonferrous materials relative to constituent materials of a fluidized bed.
Claims21
A nonferrous material sorting apparatus, comprising:
- a first screening device for screening materials of not more than a minimum reference size;
- a first sorting device for sorting the materials, which are not more than the minimum reference size and screened by the first screening device, according to a weight ratio by employing an inclined vibrating table supplied with air;
- a second screening device for screening the materials screened by the first screening device and larger than the minimum reference size into materials of at least two kinds of reference sizes larger than said minimum reference size;
- and
- a second sorting device including a fluidized bed for sorting the materials screened by the second screening device by adding solid constituent materials to said materials screened by the second screening device and sorting according to whether or not a specific gravity of the screened materials is large relative to that of said solid constituent materials of said fluidized bed.
