Working Principle. The motion of the spiral creates pool hindered settling in the bottom pool area, and the agitation of water keeps the fines suspending in the liquid, while the coarser particles settle on the spiral and be transported to the discharge which located at the top of the classifier. Then gravity flow or pumps are used to move the coarse material to the …

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) Optimum Operating Conditions of ... ="Gravity Spiral …
In this work, a novel closed spiral classifier is introduced and its performance characteristics are experimentally established for a model silica system. …
The smaller, faster ore will be able to travel a longer distance than the large particles before the rakes or spiral will pull the ground material back towards the coarse ore discharge. If the Classifier is able to pull the course ore backwards further than it can travel forwards, then eventually the bigger particles will be pulled all the way ...
A spiral classifier is a mineral processing equipment which receives an ore slurry input and performs a gravity separation process between the solids particles of ore and the water. The classifier ...
