Spiral sluice
Spiral sluice spiral chute are gravity concentrators and separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.Spiral separators are made of polyurethane lined fiber glass with wearable corundum inner surface.
Production capacity : 0.15～16t/h
Principle
When using the chute when the vertical line need to be calibrated, the ore is sent to the feed mouth. adding additional water. After adjusting the concentration of mineral by adding additional water. The paddle streams down from the high place. In bevel velocity will produce a centrifugal force. Under the action of gravity and centrifugal force, ore and sand will be separated from each other. The tailings then flow into the tailings and the sand is drain away by pump to complete the whole process of the beneficiation.
Advantages
