Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4)
Hydraulic classifiers range from simple V-shaped launders with a multiplicity of shallow settling pockets for the discharge of as many roughly sized products to the more elaborate deep-pocket machines of the hindered- settling type, having specially designed construction plates and automatic discharge of spigot products.

Spiral classifier (Fig. 1), a mechanical classifier, is one common equipment used for classification in most processing industries. This equipment has one or more spirals revolving slowly and freely on an inclined tank without touching the sides or the bottom. Its classification is based on the size and the specific gravity of the particles in ...
A spiral classifier and a hydrocyclone are the two main classification equipment. For decades, the spiral classifier has been widely used in ore dressing plants as first-generation grading equipment. As second-generation grading equipment, hydrocyclones quickly occupy a place in the grading equipment of the concentrator due …
Spiral Classifier. Spiral classifier is used for material classification with spirals used to stir and convey materials according to the difference in material settling velocities. It is a kind of gravitational and hydraulic classifiers. The specification of spiral classifiers is represented by the number and diameter of spirals.
The above is the working principle, pros and cons of hydrocyclones and spiral classifiers. In actual production, it is recommended to choose the appropriate classification equipment according to the actual situation. Hydrocyclones are suitable for processing fine-grained materials; if the amount of ore feed is uneven, a spiral classifier …
Spiral concentrators (Fig. 5.2.3) are devices to separate different solid components in slurrybased upon a combination of the solid particle density, as well as the particle's hydrodynamic properties (e.g., drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid …
