Of Spiral Concentrators

Spiral wheel gold concentrator previous next view larger image 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 get price

Spiral concentrators 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 ircon and monaite and in recent years in the recovery of fine coal

The first application of the spiral concentrator was reported in 1943 and the first all spiral plant was commissioned in the 1960s 3 spirals are typically constructed from polyurethane or fibreglass and consist of a trough winding around a vertical axis typical

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
