Spiral coal concentrators use the specific gravity of materials with different densities to separate coal, and produce a lowash coal product at high efficiency. Our highperformance Coal Spirals deliver a feed capacity of 2 STPH to 3 STPH ( mtph to mtph) per start, dependent on raw coal quality and refuse amount to be discarded.
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.
Concentrator Flows ABSTRACT Spiral concentrators are used globally in the fine coal processing industIy to segregate particles, by grnvitation, on the basis of density and size. Consisting of an open trough that twists vertically downwards about a centrnl axis, a sluny mix of particles and water is fed to the top of the concentrator.
Introduction In a recent survey of worldwide coal preparation practices, it was reported that spiral concentrators treat 6% of the coal treated in processing plants (Kempnich, 2003). The application is typically associated with cleaning the 1 · mm fraction of the plant feed. The popularity of spiral concentrators is due to their ...

Wet Spiral Separators. Spiral separators of the wet type, also called spiral concentrators, are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle''s hydrodynamic properties ( drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to ...
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. NobeleMEIR also offers lab sized spirals: in single or double starts, and either: 3, 5, 6 and 7 turns.
Coal beneficiation Spiral Concentrator and Slurry Jig Gold Ore Crusher. Spiral concentrator was found to have an edge over slurry jig both in quality and quantity of clean to beneficiation of low grade coking coal at finer sizes. CP/ of Iron Ore. Separating Gold, Lead Ore. Gold ore washing machine.
Coal/Mica Spiral Spiral Concentrators Larger diameter units than the mineralspiral series, these spirals are designed to take advantage of the particle shape differences. Takeoff splitters at different points down the helix give this spiral a high capacity to remove refuse or siliceous contaminants from the coal or the mica.

When to use a Gravity Spiral Concentrator. The Humphreys Spiral has been successfully applied to recovery of chromite from chrome sands, rutile, ilmenite, and zircon from sand deposits, tantalum minerals and lepidolite from their ores, gravity concentration of base metal ores and in the cleaning of fine coal.
Heavy minerals such as ilmenite or hematite settle out rapidly in a spiral concentrator and they should be removed as soon as a good wide band forms. Since the concentrate band is wider at the top, splitters near the top of the spiral concentrator should be opened wider than those near the bottom.
