Spiral chute is the best concentrating equipment, especially for concentrating sand ore in seashore and riverside. It is made of the fiberglass lined with wear-resistant polyurethane and corundum cover; The advantages are light, moisture proof, and anti-rust,corrosive proof and no noise, properly suitable for the different feeding particle sizes and grades.

The uniform ore slurry is slowly fed to the spiral groove surface through the ore feeding trough installed at the head end of the spiral trough for sorting. The end of the spiral groove is equipped with a valve block-type product intercepting groove, and the sorted products are divided into three types according to the grade along the radial direction. The position of the regulating valve block is used to change the intercepting width of each product, and the product gathering bucket collects and derives the intercepted multi-head ore streams. The cross-section and the slope change of the curve are especially suitable for the selection of fine particle materials.

Spiral chute is suitable for the treatment of the 0.6-0.03mm lode and placer, but high mud content is bad for separation. At present, the spiral chute has been widely used in the treatment of iron ore, tungsten, tin ore, niobium tantalum ore, coastal and riverside placer, and gold ore.

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