Product Description

Mini Lab gold spiral concentrator/ Laboratory Gravity Chute for Gold Mining 

General Introduction of Spiral Chute

Spiral chute uses gravity to separate particles of different densities.
It is used globally in the mineral processing industry, consists of an open trough that twists downward in helix configuration about a central axis.

Application of Spiral Chute

It is used to separate the iron, tin, wolfrmite, tantalum, niobium, gold ore of the size between 0.3 and 0.02mm, and the other metals and nonmetal minerals with different gravity property .

Working principle 

When working, particles are fed to the top of the spiral chute and are separated radially on the basis of density and size as the slurry gravitates downward. In order to have a good separation, there should be a difference in specific gravity of at least 1.0. 

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.


Main Features

1.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.

2. It is a high efficiency gravity concentrator of the international advanced standard.

3. Simple structure, steady working condition, reliable operation, easy maintenance, small floor area, high capacity.
