What’s a Spiral Separator?

A spiral chute is used to separate fine-grained iron, tin, tungsten, tantalum, niobium, gold ore, coal mine, monazite, rutile, zircon, and other metal and non-metallic minerals with sufficient specific gravity difference. The sorting process is stable and easy to control, the allowable range of feed concentration is wide, the enrichment ratio is high and the recovery rate is high.

Working Principle Of Spiral Separator

The spiral chute mainly uses the inertial centrifugal force generated by the minerals of different densities in the spiral rotation to achieve the separation of light and heavy minerals. Because of its simple equipment structure, low power consumption, and large processing capacity, it is widely used in the gravity separation process. Chute beneficiation belongs to the bevel flow separation process. The slurry is given to a certainly inclined chute. Under the impetus of water flow, the ore particles are loose and layered. The upper layer of light minerals is quickly discharged from the tank, and the lower layer of heavy minerals is retained in the tank or discharged from the lower part at a low speed. After that, concentrate and tailings are obtained.

Advantages Of Spiral Separator

  • It is widely used in the treatment of tungsten, tin, gold, platinum, iron and some rare metal ores, especially in the treatment of low-grade sand ores.
  • The spiral chutes has stable performance, clear ore separation, high enrichment ratio and recovery rate.
  • Moisture-proof, rust-proof, corrosion-resistant, no power required, no moving parts, no noise, creating a good operating environment.
Spiral Separator


The Spiral Separator consists of a spiral separation channel, an inlet, and a drive unit, which utilises the differences in the physical properties of the different components through the movement of the material in the spiral channel to achieve separation.
