A Review of Spiral Technology for Fine Gravity Beneficiation

Fig. 2 indicates the performance of the spiral separator under the effect of both feed pulp density and feed rate. It is evident that a pulp density in the range of 36 to 40% solids is near the optimum, in fact these data suggest that feed pulp densities >48% are detrimental to the performance. This is due to the higher apparent...

Spiral separator - Wikipedia

Conversely, light particles stay towards the outside of the spiral, with the water, and quickly reach the bottom. At the bottom, a "cut" is made with a set of adjustable bars, channels, or slots, separating the low and high density parts. Many things can be done to improve the separation efficiency, including: changing the rate of...
