ADVANTAGES

01  High efficiency, high recovery and accurate ore separation, no need of power;

02  Light weight, rust, wear and corrosion ressistance;

03  Low operation cost and long service life;

04  Strong adapability to the variation of feeding quantity, density, particle size and grade.

PRODUCT STRUCTURE

Spiral Chute principle

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.
