SX7 & MX7 Multi Stage Coal Spiral Concentrators Incorporating two stages of spiralling into a single assembly with auto rejection channel and gully. What Multotec offers: Test work on spiral concentrators, laboratories or pilot plants; Consultation regarding spirals and plants; Design assistance to clients; Commissioning of spiral
Our spiral separators have a diameter of +/- 950 mm. Gravity Separators for coal. Our single- and double-stage spiral separators are optimised for coal particles in the size range of 1 to 0.1 mm,
Multotec has designed and optimised both single (SX4) and 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
SX7 and MX7 Coal Spiral Concentrators. Multotec has designed and optimised the double stage MX7 coal spiral concentrators to process feed with a size range of 2.0 mm to 0.1 mm for difficult-to-wash coal. The 2-stage spirals, the SX7 and MX7, incorporate two stages of spiralling into a single spiral assembly, reducing plant height and floor space requirements ultimately reducing capital and operating costs.
Multotec has designed and optimised both single (SX4) and 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.
To address this, two-stage compound spirals have been designed in which clean coal and middlings are retreated in a second stage of spirals and the middlings from this spiral are recycled to the first spiral.
Spiral concentrators require relatively coarse material to effectively concentrate valuables as well as offering greater simplicity for especially higher grade feeds. two-stage-cleaning of
Spiral concentrators are gravity separators usually separating particle sizes between 0.1 and 2 mm in a water carrier medium1,2. The capacities of the spiral concentrators range between 1 and 3 t/h dry solids and recently in excess of 7 t/h in the case of high capacity spiral concentrators when treating typical heavy mineral beach sands

Spiral concentrators have been widely used in coal preparation plants in Illinois and elsewhere to clean 1 mm ×150 m particle size coal fraction. The major factors which have made spiral concentrator so popular include its low capital and operating cost, no chemical reagent or dense medium requirement, and the ease of operation/maintenance.

double stage MX7 spirals, and is capable of processing 36 tons of coal per hour to the spirals. Benefits: The test plants are stand-alone units, and can be skid mounted Easily erected on site, with three primary modules The flowsheet may be adapted to suit specific applications Plug and Play capability
WOC-spiral concentrator circuit Due to the inefficiencies of a single-stage WOC, industrial applications utilize a two-stage process with a recycle stream, which significantly improves process efficiencies.
Luttrell et al. (1998 and 2007) examined a variety of circuits for two-stage spiral operation and concluded that a rougher-cleaner circuit, where the middling and clean streams are remixed and
16.6.3 Spiral Concentrator. The spiral concentrator first appeared as a production unit in 1943 in the form of the Humphrey Spiral for the separation of chrome-bearing sands in Oregon. By the 1950s, spirals were the standard primary wet gravity separation unit in the Australian mineral sands industry.
was commissioned in 1982. The 1000 tph plant was a single two-stage circuit employing Wright helical sluices rather than Reichert cones. Metallurgical test work conducted on site had shown these units to be more efficient and a two-stage sluice circuit matched or bettered four stages of cones. There was also no requirement for dilution water.
