  • Spiral separator - Wikipedia

    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 (e.g. 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 ...

  • Gravity Spiral Concentrator Working Principle

    Spiral Concentrator. Spiral concentrators are modem, high capacity, low cost units developed for the concentration of low grade ores. Spirals consist of a single or double helical sluice wrapped around a central support with a wash water channel and a series of concentrate take-off ports placed at regular intervals along the spiral (Figure 17).

  • Case study: high capacity spiral J concentrators

    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 Wheel Gold Concentrator

    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. It is usually mounted on a frame with a wash water bar running laterally from the one side to the center.

  • Spiral Concentrator - Outotec

    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.
