                         Gravity separation spiral chute for non-metallic minerals


spiral chute is gravity separating device.It's suitable for separating different proportions non-ferrous metal,rare metal and non-metallic minerals,such as iron ore,gold ore ilmenite,chromite,pyrites,zircon,rutile,monazite,phosphorite,tungsten ore,tine,tantalum,niobium ore.

Pay attention to the picture above: it's a gravity separating production line. pictures shows the spiral chutes and shaking tables. After first gravity separating by the spiral chutes, some essence mineral are separated; The shaking tables could seprate the rest mineral and help reseparate it again.

And the size of feeding material should be 0.3-0.02mm.
spiral chute could be polyurethane coating,the materisl could be fiber glass according to your order.

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.


Advantages and features:
♥ Reasonable structure and small occupation area
♥ High recovery, high efficiency, and precise separation
♥ Non-required power
♥ Light in weight, anti corrosion, rust and wear resistant
♥ Simple installation and Minimal maintenance requirements
♥ Low operating cost and long working life
♥ Reliable running with minimal operator attention
♥ Strong adaptability to fluctuation of feeding amount, density, size and grade
♥ The surface of corundum forms strong friction the concentration effect surpass plastic surface
