Mineral Gravity Separator Spiral Chute for Gold Iron Ore Separation
Description of Spiral Chute
Spiral Chute is applicable for separation of granularity ranged from 4mm to 0.02mm metallic minerals such as iron, ilmenite, chromite, tungsten-tin ore, niobium-tantalum ore, gold placer, seashore monazite, rutile and zircon as well as other metallic and non-metallic minerals with adequate difference of specific gravity. For the seaside, riverside, sand beach, the stream of placer mining, it is the best equipment of all.
Features of Spiral Chute
1. Reasonable structure and small occupation area.
2. High recovery, high efficiency, and precise separation.
3. Light in weight, rust 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.
Working principle of Spiral Chute
Spiral Chute is working under the force of water flow, gravity, inertial centrifuge and friction. Slurry is pumped to the top of the spiral, and it enters a feed distributor that evenly distributes the feed to each spiral concentrator. The design and shape of the spiral make it work, when combined with gravitational acceleration. As the slurry travels the spiraling path down the spiral, mineral grains settle and start sorting according to size, density and to a lesser extend shape. Low density particles are carried with the bulk of the water towards the outside of the spiral, while particles with the greatest density migrate towards the inside of the spiral.
