How do spiral concentrators work?
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. Spiral concentrators are used in many mineral processing applications. For instance, they're used to process heavy mineral sand deposits, more specifically …
