widely use gravity method Spiral Concentrator for gold, chrome, tin, mineral processing

Introduction of spiral concentrator from Deya machinery

Spiral concentrators are devices to separate solid components in a slurry, based 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 particles that have come out of suspension.

Working principle of spiral concentrators

As larger and heavier particles sink to the bottom of the sluice faster and experience more drag from the bottom, they travel slower, and so move towards the center of the spiral. Conversely, light particles stay towards the outside of the spiral, with the water, and quickly reach the bottom. At the bottom, a “cut” is made with a set of adjustable bars, channels, or slots, separating the low and high density parts. Many things can be done to improve the separation efficiency, including:

-changing the rate of material feed

-changing the grain size of the material

-changing the slurry mass percentage

-adjusting the cutter bar positions

-running the output of one spiral separator (often, a third, intermediate, cut) through a second.

-adding wash water inlets along the length of the spiral, to aid in separating light minerals

-adding multiple outlets along the length, to improve the ability of the spiral to remove heavy contaminants

-adding ridges on the sluice at an angle to the direction of flow.

Applications of spiral concentrators

Typical spiral concentrators will use a slurry from about 20%-40% solids by weight, with a particle size somewhere between 1.5-.075 mm (17-340 mesh), though somewhat larger particle sizes are sometimes used. For good separation, the density difference between the heavy minerals and the light minerals in the feedstock should be at least 1 g/cm3; and because the separation is dependent upon size and density, spiral separators are most effective at purifying ore if its particles are of uniform size and shape. A spiral separator may process a couple tons per hour of ore, per flight, and multiple flights may be stacked in the same space as one, to improve capacity.
