Spiral classifier is a common classification equipment used in mineral processing plants. It has the characteristics of simple structure, reliable operation, large processing capacity, stable classification area and high classification efficiency. Below we briefly introduce its importance, working principle, application and main classification.

Traditional gravity classifiers that leverage differential settling velocities in the gravitational field are bulky and ineffective for particles less than 150 μ m.In this study, a newly introduced compact enhanced gravity Closed Spiral Classifier (CSC) is tested experimentally for the classification of slurries containing silica or iron ore fines.

(1) The spiral blades at the lower end of the submerged spiral classifier are all immersed in the pulp with the largest classification area, which is applicable to the processing of fine materials. (2) The spiral blades at the lower end of the high- spiral classifier are partially immersed in the pulp with smaller classification area.

Because users' needs vary so greatly, the Classifier is available in a wide range of spiral diameters and pitches, tank shapes and lengths allowing exact compliance with each user's classification requirements. Spiral diameters (0.3 m to 2.25 m): Important in establishing a correct balance between overflow and raking capacity.

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 …

From Fig. 4, we get the following observations: (i) The concept drift online classifiers significantly outperform the noise-resilient classifiers; (ii) Specifically, on SEA data set, the performance of Logistic is comparative to hinge-SVM, which outperforms other base classifiers. Logistic is the best base classifier on Hyperplane dataset; (iii ...

Operating the spiral classifier at a feed rate, spiral speed and washing time of 6 t, 25 rev/min, and 30 min, respectively, yielded Mn grade of 53%.

During separation, the slurry enters the spiral through a feed box and then flows on to the spiral surface. As the slurry travels down the spiral, mineral grains settle and sort according to size, shape, and specific gravity. Spiral separation uses a flowing film principle based on the size and specific gravity difference present in a mineral ...

The spiral classifier was originally developed for closed circuit grinding It has since been applied very successfully to other classification duties where a two-product size split is …

Spirals have become one of the most popular methods for treating fine coal. Unfortunately, spirals tend to produce an undesirably high specific gravity cut point and often misplace significant amounts of coal and/or rock. In the present study, a process-engineering tool known as linear circuit analysis was used to identify problems with …

The other problem that these classifiers have is that they are easily overloaded. An overloaded classifier can quickly deteriorate into a sanded-up classifier. Once that happens the results are lost operating …

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. Material is discharged from the upper by spiral, so as to finish the grading work.
