Abstract:
    The utility model relates to a spiral chute concentrator, especially for the separation of nonferrous metallic, ferrous metallic, and nonmetallic minerals. The cross section of the spiral chute has a novel, unique complex curve by which the single processing capacity has been significantly enhanced (15 to 40 ton/machine hour), mainly employing that the difference among gravity, centrifugal force, friction effecting on the minerals and the surface of the ore vein during the mineral flow process. The concentrator has simple structure, large processing capacity, wide separation range of particle degree (4 to 0.04 mm), and can save water and electric energy, and can be easily operated and widely applied, and needs no external power, and has long working life.
