Spiral Concentrator

An interesting variation of the spiral concentrator is the rotary table this device is available from a variety of manufacturers under many trade names basically the rotary table consists of a flat circular plate in which a spiral pattern has been molded or cut it is usually mounted on a frame with a wash water bar running laterally from the one side to the center when operating the

Where r is the radial distance from the central column r i and r o are inner and outer radius of the trough from the centerline 3 fluid flow on the spiral trough and generation of secondary flow the geometrical configuration of spiral concentrator generates a unique flow pattern on the trough surface which helps in easy and efficient separation of material into heavies and lights

Spiral concentrators have found many varied applications in mineral processing but perhaps their most extensive application has been in the treatment of heavy mineral sand deposits such as those carrying ilmenite rutile zircon and monazite and in recent years in the recovery of fine coal

Spiral concentrators are normally used in banks of multiple spirals typical capacities for spirals run from 13 tons per hour of feed for minerals and 35 tons per hour for coal typical construction of a spiral concentrator is fiberglass and urethane to reduce wear from abrasion

Spiral concentrators are gravity separators usually separating particle sizes between 01 and 2 mm in a water carrier medium12 the capacities of the spiral concentrators range between 1 and 3 th dry solids and recently in excess of 7 th in the case of high capacity spiral concentrators when treating typical heavy mineral beach sands
