How do spiral concentrators work?
Two or more spirals are built around one main central column, thus increasing the amount of material that can be processed by a single unit. Spiral concentrators are gravity-based and used to separate low-density granular and sandy (from 18 mesh to 200 mesh—1 mm to 0.0757 μm) materials from higher-density materials.
