Spiral sluice used for separating various minerals , mine equipment for gold processing
Spiral sluice(spiral chute) is gravity separation equipment separating different weight mineral by intertial centrifugal force pulp produced in helix turing motion according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.Spiral separators are made of polyurethane lined fiber glass with wearable corundum inner surface.
Our spiral concentrator (spiral chute) is made of the fiberglass lined with wear-resistant resin and emery cover; the advantages are light, moisture proof, anti-rust, wear proof, anti corrosion, no noise and non power required.
How is woks: Ore pulps are uniformly fed into machine and form different layers as they pass across chute. Heavy minerals precipitate to bottom and are moved toward inner edge by the comprehensive action of various forces; light minerals are moved toward outer inner due to the speedy rotation. As a result, mineral particles with different density are divided into three zones---concentrate, middling and tailing.

Our Advantages
Spiral chute present advantages as follows:
Less floor space; easy and stable operation; rational configuration; convenient installation; high processing capacity and efficiency; moisture proof; antirust; corrosion resistant; adaptive and noiseless, etc.
Working principle
Gold spiral separator 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.
Applications
Professional mining machine spiral sluice spiral chute
It widely used in enrichment of particle size 0.3-0.02mm fine minerals like iron, tin, chromite, ilmenite, tungsten, zinc, tantalum-niobium, gold, coal , monazite, rutile, zircon and other low-grade ores, and non-metallic minerals which have a big enough specific gravity difference.
