Spiral Separator / Spiral Chute is the highly efficient equipment for gravity separation, which has advanced technology both at home and abroad. It is suitable for separating 0.4--0.02 mm size fine minerals such as iron ore, titanium ore, chrome ore, pyrite, zircon, monazite, rutile, phosphorus ore, tungsten, tin, phosphorus B ore, niobium, tantalum ore as well as other non-ferrous metals, rare metals and non-metallic minerals with proportion differences. It is the best equipment of mining and beneficiation machines, especially, used in the placer mining of waterfront, river, sand beach and creek road.
Features:
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.
Structure&Working Principle:
Spiral chute is working under the 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.
