THE EFFECT OF REPULPING ON THE SX7 SPIRAL

Spiral concentrator flows display laminar to increasingly turbulent behavior. The primary flow is that of the slurry descending the inclined portion of the trough. Secondary flow occurs radially across the trough. During their passage through a spiral, particles are subjected to hydrodynamic drag and lift, friction, gravity and centrifugal ...

Gravity/Density Concentrator, Spiral Concentrator

The spiral concentrator is a modern device that works on a combination of solid particle density and its hydrodynamic dragging properties. The spirals consist of a single or double helical conduit or sluice wrapped around a central collection column. It is used for concentration of low-grade ores and industrial minerals in slurry form.
