Spiral Separator suppliers Description: Spiral Gravity Chutes is one of the gravity concentrators, which separate minerals according to different specific gravity according to dwing the movement in response to gravity, centrifugal force and other forces in the fluid medium. It has extremely good performance and effects in processing placer of beach, riverside, seashore and stream. Spiral Gravity Chutes is made of polyurethane lined fiber glass with wearable corundum inner surface. Generally there are 5 turns in one start, single, double, triple and quadruple starts available per column to suit capacity requirments. Features: 1. Reasonable structure and small occupation area; 2. High recovery, high efficiency, and precise separation; 3. Light in weight, rush and corrosion resistant; 4. Simple installation and minimal maintenance requirements; 5. Low operating cost and long operating life; 6. Reliable running with minimal operator attention; 7. Strong adaptability to fluctuation of feeding amount, density, size and grade.http://www.ore-magnetic-mining.....com/gravity-mining-
