Spiral concentrators are normally used in banks of multiple spirals. Typical capacities for spirals run from 1-3 tons per hour of feed for minerals and 3-5 tons per hour for coal. Typical construction of a spiral concentrator is fiberglass and urethane to reduce wear from abrasion.
double stage (MX7 and SX7) Coal Spiral Concentrators to treat a size range of 2.0 to 0.1 mm. The Multotec two-stage spirals (MX7 and SX7) incorporate two stages of spiralling into a single spiral assembly. This has the advantage of reduced plant height and floor space requirements, as well as reduced capital and operating costs.
Oct 22, 2016· This results in a significant amount of fine coal reporting to the plant which also requires to be processed at low relative densities in order to yield coking coal. Processing of the coal at low relative density is very difficult to achieve, especially on the fine coal (-1+0.1 mm size fraction).
