Beneficiation spiral chute integrates features of spiral concentrator, shaking table, and centrifugal separator. It the best equipment for mineral processing, especially used for mining sands in coastal, river, sand beach, river road, etc. Beneficiation spiral chute is adapted to process alluvial deposit, especially flat materials with high monomer dissociation degree of useful minerals. Besides, since minerals containing high mud have low concentrate quality, so they must be de-slimed and graded before entering into the beneficiation spiral chute. The working features of beneficiation spiral chute is that the concentrate, middling and tailings are gotten at the end of the equipment, and the sorting process does not need washing water. Spiral chute is the main component of the device, which is made of polyurethane wear-resistant plastic or mixed artificial corundum resin. Its liner is made of FRP a wear-resistant material. On the top end of beneficiation spiral chute, there is a mineral separation device and a feed tray; at the lower part of beneficiation spiral chute, there is a products interceptor and a trough for receiving ores. The whole equipment by pioneers manufacturer stands vertically though still frame.
