vertical spiral separation of sand
Important variables in spiral design are the pitch (vertical height between turns), profile, position and number of concentrate cutters and the use of washwater additions. Following the choice of spiral, it is necessary to determine the size range of material to be treated and the preparation of that material for spiral separation.
A review of gas-liquid separation technologies: Separation …
The separation principle of the axial-flow guide-vane gas-liquid cyclone separator is that the gas-liquid phase produces a turbulent flow after flowing through the guide vane. Then, the fluid leaves the guide vane at a high speed and undergoes a three-dimensional spiral motion in the separation chamber.
Impact of spiral separator geometrical parameters on the …
The lower slope of sluice and larger height made separation even more efficient. Analysis of separation of model material, that is the mix of sand and magnetite, showed that in this case the existence of additional water sluice does not have an impact on product separation and best results were obtained in the Reichert LG-7 spiral separator.

Spiral separators, Gravity Separation | GSL
Spiral separators, or spirals for short, are a versatile method of gravity separation that can deal with a comparatively wide size range. Separation is achieved as a result of centrifugal forces induced by slurry running down the spiral, which forces lighter minerals to the outer bend whilst heavier minerals stay closer to the central axis of the spiral.
