Spiral Concentrator
A spiral concentrator is a device that relies on gravity to separate material in a slurry feed. The light density granules are separated from the heavier density material. Why spiral concentrators are used? Spiral concentrators are low-cost devices, used in mineral processing to process heavy mineral sand deposits, usually containing minerals ...

Investigation of residence time and fluid volume in spiral
Results of tracer tests conducted on a WW6Plus spiral concentrator, operating only with water, show that the fluid remains for approximately 7.5 s in the spiral trough and that the fluid transport mechanism is of plug-flow type. Direct measurements show that the volume retained in the spiral trough varies proportionally to the spiral feed rate ...

Spiral Concentrator Interface Monitoring through Image …
The optimal splitter position in a spiral concentrator is dependent on the interface position(s) between concentrate, middlings and/or gangue streams in the spiral trough. Image processing methods can be used to detect interface positions, which could be used in spiral concentrator operation monitoring and control.

Selenite Spiral Tower 4 Inches (1 Piece)
Selenite, sometimes also called satin spar, is a variety of gypsum that tends to grow either in long fibrous or flat plate-like crystals, which can result in opaque or translucent pieces. An extremely soft mineral, selenite will often contain small inclusions of other minerals or internal cleaving where different crystal shapes meet.

How do spiral concentrators work?
In order to obtain good separation, there should be at least 1.0 SG of difference (mainly ranging from 20–40% solids). This range should provide maximum efficiency, depending on the characteristics of the mineral being processed. The only equipment required is typically some slurry pumps for the slurry to be separa…See more on multotec
