Spiral coal concentrators use the specific gravity of materials with different densities to separate coal, and produce a low-ash coal product at high efficiency. Our high-performance Coal Spirals deliver a feed capacity of 2 STPH to 3 STPH (1.8 mtph to 2.7 mtph) per start, dependent on raw coal quality and refuse amount to be discarded.
Feb 26, 2018· Spiral concentrators are simple low energy-consuming devices used for mineral separation mainly on the basis of density or by shape. https://bit.ly/2W62joo==...
Spiral Concentrator. Spirals in coal processing are high capacity, lightweight fiberglass construction, use no power, use no reagents and effectively remove pyrites from coal. Most spirals are available in single start, double start or triple start versions, giving two or three times the...
Mar 26, 2016· 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.
Finally gangue is discharged from inner edge of spiral chute and clean coal is discharged from outer edge to separate clean coal and gangue. Spiral separator for coal slime is widely used for coarse coal clime treatment in coal preparation plant, especially suitable for 2mm-0.1mm coarse coal slime separation in thermal coal preparation plant.
Outotec spiral concentrators are used in most applications, particularly for concentrating low-grade ores. Manufactured from lightweight, corrosion and abrasion-resistant materials, our spirals require minimal maintenance and upkeep. Gives you an effective and low-cost solution for gravity separation.

The number of turns on spiral concentrators varies typically from 5-7 and the trough width from 0.25-0.35m. The mainstream descent angle varies radially and is governed by the spiral pitch, defined as the vertical height loss per revolution of the helix. The LD9 coal-processing unit examined in this paper has a pitch of 0.273m, trough
Spiral concentrators are used for a number of mineral processing applications. They're extensively used to process heavy mineral sand deposits, including monazite, zircon, ilmenite and rutile deposits. recently, spiral concentrators have been widely used to recover fine coal as well as gold, iron ore. Get Price.
Apr 05, 2021· "As far as capital equipment costs, they will be more expensive than spirals or the RC, but it's the Cadillac of fine coal recovery systems these days," Bethell said. Mineral Technologies' LC3 spiral concentrator targets a cut point of 1.45 to 1.60 with a capacity of 3.5 mtph pr start (typically 2 to 2.5 mtph/start) with a pulp density ...
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.
