PARTICLE FLOW MODELLING ON SPIRAL

Spiral concentrators, used globally in the mineral processing industry, consist of an open trough that twists downward in helix configuration about a central axis. Particles fed to the top of the concentrator are separated radially on the basis of density and size as the slurry gravitates downward. To improve performance, CFD studies validated against
