Gravity Spiral Concentrator Working Principle

Feed is split evenly to all spirals. At one plant 21 rows of 12 spirals each are fed by one pump. The Humphreys Spiral Concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity.

SPIRAL SERIES | Selecta

It is possible to deliver the spiral separators with 2 or 3 outlets, depending on the seeds you have to separate. The standard model has 2 outlets at 180 angle. By using the insert set of brushes the extra outlet (third outlet) in the outer spiral for an extra separation of the "swug-out seeds" is not required any more for the majority of seeds.
