Particles below a certain size and density are carried away with the water-flow, whereas the coarser and heavier particles settle. Basically the different wet classifiers are gravity settling tank, cone classifier, double cone classifier, hydrocyclone classifier, spiral classifier, and rake classifier. Gravity settling tank is the simplest type ...

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)
Whether in classification efficiency or product accuracy, spiral classifiers are better than hydrocyclones. A large part of the reason is that if the pressure of the hydrocyclones does not meet the standard, the final material discharge position will change, greatly affecting the efficiency of its … See more

We recommend a maximum feed pressure of 125kPa for fine feed, and a maximum of 100kPa for coarse feed, to prevent excessive wear. But for fine particles or dilute feeds, the maximum pressure can be as high as 300kPa for the smaller cyclones – 400mmØ and less. Recommended maximum feed pressures are –. Cyclone Diameter.

Hydrocyclone structure. Hydrocyclone Working Principle The hydro cyclone pump (or height difference) rotates the slurry into the cylinder along the Tangent Direction with a certain pressure (generally 0.5 ~ 2.5 kg/cm) and flow rate (about 5 ~ 12 m / s), and then the slurry rotates along the cylinder wall at a very fast speed to create centrifugal force.
Basics of a Hydrocyclone. Hydrocyclones (also referred to as cyclones) are an efficient way to separate slurries. With no moving parts, they depend on the feed pressure, or velocity, into the cyclone to generate a centripetal force. This centripetal force allows the cyclone to separate coarse or dense particles from fine particles.
