Spiral classifiers are often combined with ball mills to form a closed-circuit cycle to separate ore sands, or to classify ore sands and fine mud in mineral processing plants. It is also used for or washing clay sand, silica sand, tailings dehydration, tailings water separation, etc. It is one of the main equipment for mineral processing.
Referred to as the classifier or horizontal spiral classifier, the spiral classifier is one kind of equipment for the ore processing plant. It is the device for mechanical classification based on the principle that the specific gravity of a solid particle is different, therefore the rate at which it precipitates in a liquid also is different.
Mineral processing experts suggest that the single spiral classifier should be selected as far as possible under the determined processing capacity. According to statistics, the working load of the double spiral classifier is 0.6-0.75 times than that of the single spiral classifier, and the efficiency is relatively low.
Spiral operation and partition curves of the particles. A spiral classifier is shown in Fig. 1. The spiral feed that consists of a water-slurry of ground ore enters the top of the spiral. As the slurry enters the spiral various forces (Burt, 1984) act on the particles to operate the separation between light, heavy, coarse and fine particles.

The Spiral classifier was operated in batch mode.
A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …
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.

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 …
