ABSTRACT:
Differential rate screening processes and apparatuses for continuously screening a feed of particulate material having particles distributed among a plurality of substreams each of a different size class. A stream of feed is separated by causing part of each of at least two undersize substreams to pass through the apertures of a screening member at partial flow rates providing control over the size distribution of a throughs stream. The relative flow rates at which the undersize substreams pass into the throughs stream is controlled to provide substantially a preselected size distribution in a particulate product stream.
