Spiral separator project on degree basis

Mar 26, 2016 The Humphreys Spiral Concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity. This concentrator is a spiral conduit of modified semi-circular cross-section, with outlets for removal of concentrate and middling
