Disadvantage of spiral concentrator

15.5.3 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 1950’s, spirals were the standard primary wet gravity separation unit in the Australian mineral sands industry

    Gravity Spiral Concentrator Working Principle

    Mar 26, 2016 Advantages of spiral concentrators include low cost, long equipment life, low space requirements, and good recovery of fine material. They can also be checked visually to determine if the material is separating properly. For maximum operating efficiency, feed density should remain constant, the particle-size distribution of the feed should be

    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 concentrators are a gravity based concentrating device, that separates light density granular and sandy (18 mesh to 200 mesh (1 mm to 0.075 microns)) consistency material from heavier density material. In order to have a good separation, there should be a difference in SG's of at least 1.0
