Spiral Classifier
The spiral classifier is one of the size-classifying equipment for the mining industry. It is a kind of equipment for mineral classification based on the principle that the specific gravity of solid particles and the speed of precipitation in the liquid is different.
Spiral Classifier Structure, Working Principle, Feature, …
Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel.

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) Optimum Operating Conditions of ... ="Gravity Spiral …

(PDF) Optimisation of Operational Parameters of a Spiral Classifier
The control parameters of the spiral classifier were critically observed and studied to understand spiral classifier operation. The adjustable parameters at the classifier section were the feed particle size, amount of water supplied to the classifier, angle of inclination of the classifier, feed tonnage, the speed of the spirals and the ...
Spiral classifier manufacturers | Screw Classifier …
The key component of a spiral classifier is the main shaft, which is carefully designed and selected to prevent deflection due to the spiral weight and the thrust load imposed by the spiral during raking. Large diameter, seamless steel, tubular shaft with sufficient wall thickness are used for minimum deflection.
An operational model for a spiral classifier
Spiral classifiers. A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough (Burt, 1984). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.
