Spirals are widely used in mineral processing as a method for pre-concentration and have proven to be metallurgically efficient and cost-effective.An analytical approach to explain complex flow in spiral,,14-06-2021· The basic design of a spiral concentrator has a central column and a spiral trough attached to it with a feeding arrangement at the top such that the feed flows down the channel around the central column. The number of turns varies from 3 to 7 depending on the duty and the type of material being processed ( Burt, 1984 ).Case study: high capacity spiral J concentrators,Spiral concentrators are gravity separators usually separating particle sizes between 0.1 and 2 mm in a water carrier medium1,2. The capacities of the spiral concentrators range between 1 and 3 t/h dry solids and recently in excess of 7 t/h in the case of high capacity spiral concentrators when treating typical heavy mineral beach sands deposits3.Spiral Concentrator - Metso Outotec,In a spiral, heavy mineral concentrate is selectively directed into the spiral trough near the inside of the spiral surface through the use of adjustable product splitters. The concentrate then flows through product discharge outlet ports down the length of the helix.
