1.High efficiency Spiral Chute 2.Simple fixed & Less space 3.Reasonable stucture 4.Concentrating even 5.Separated clearly Spiral ChuteSpiral Chute uses gravity to separate particles of different densities. Features and Benefits of Exway Spiral Chute:The advantage is reasonable structure, simple fixed, less space, easily operated, concentrating even, separated clearly, high efficient. The product is made of the chlorine plastic, the advantage is light, moisture proof, antirust, corrosion proof, properly suitable for the changing of the feeding size and chrome, granularity, grade, no noisy. Application of Exway Spiral Chute:Spiral Chute, which is the best concentrating equipment, especially for concentrating of the sand 0re of the sea share, riverside, sand, rill is better. It is used globally in the mineral processing industry, consists of an open trough that twists downward in helix configuration about a central axis. Particles fed to the top of the concentrator are separtated radially on the basis of density and size as the slurry gravitates downward.Working Principle of Exway Spiral Chute:

In order to have a good separation, there should be a difference in Specific Gravity's of at least 1.0. One main benefit of spiral concentrators is they have no moving parts. The feed range, in percent solids, to a spiral ranges from 20% solids up to 40% solids. Depending upon the material characteristics, a maximum efficiency will usually be reached somewhere in this range. All that is required are some slurry pumps, the slurry to be separated and the banks of spirals with a feed distributor.

Slurry is pumped to the top of the spiral (typically 13' to 15' from the floor), 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 (perimeter), while particles with the greatest density migrate towards the inside of the spiral.
