2. 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.

Contact Now +86-. Published time：27 September 2023. The spiral classifier is a commonly used equipment for mineral processing (sand washing). It is often paired with a ball mill to form a closed-circuit circulation to divert ore. It is also used in gravity concentrators to classify ore and fine mud, ore slurry in metal mineral ...

Ghana Manganese Company (GMC) has renovated their oxide washing plant by integrating it with a spiral classifier to make a batch system operating process. Particle size of <3.35mm (Mn grade of 43-47%) obtained from the primary section of the plant served as feed to the classifier and with the plant condition (i.e. at 60 min washing time, 30 ...

This work provides a comparison between the most commonly used classification equipment in the treatment of minerals - hydrocyclones and spiral classifiers - considering their applications and costs. Although in use for decades in the mining industry, spiral classifiers have lost a lot of their importance due to the development of cyclones. This …

Classifier Slope. In general the classifier should be installed with a slope of from 3″ to 4″ in 1 ft. The steeper the slope the less the pool area of a given size classifier. The less the pool area the less the capacity. The maximum capacity for any mesh separation is obtained at a slope of about 3″ in 1 ft.

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)

This classifiers are of the spiral and screw family. It is of interest that the Homestake, long a user of cones for dewatering and classifying, selected mechanical bowl classifiers for their new mill addition. In the Homestake's enlarged and rearranged plant are 10 cones of local make, 7 ft. in diameter and with 65-deg. sides.

The Closed Spiral Classifier (CSC) assembly consisted of a few turns of spiral with one inlet and two outlets. The spiral had a uniform rectangular cross section with a width of 2 cm and a height of 0.5 cm. The outer radius of curvature of spiral was 5 cm. The closed spiral classifier was 3D printed in modular components using …

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 & …

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 …

Spiral Classifiers. The shape of the spiral classifier tanks is usually rectangular (Figure 13.1). The feed is introduced at a position about halfway along the length of the settling tank. The tank slopes range from 14° to 18°. The slope is adjusted such that the top end is higher than the height of the overflow weir. The spirals impede the ...
