Disc Sprial Classifier Mecine

The spiral classifier rotates at a low speed through the spiral to stir the pulp to make the fine particles suspend to the top and overflow to the overflow . In contrast, the coarse particles sink to the bottom of the tank and are conveyed to the discharge port by the screw to be discharged as returned sand, while The hydrocyclone needs to

Particle Size Classification Equipment

In the past, mechanical classifiers were usually selected to operate in closed circuit with grinding mills. These devices require much floor space and have been essentially replaced in large plants, as well as small, by hydrocyclones. Since classification is a potential plant bottleneck, it is recommended that the cyclone feed system be provided with redundant …

Separators, Classifiers, and Screeners Information

Rake, spiral, and bowl classifiers use mechanical action to dewater, deslime or separate coarse bulk materials from finer materials or liquids. Drag classifiers consist of a chain-link conveyor or endless belt that is dragged through a solid-liquid mixture. Rake classifiers lift solid-liquid mixtures up onto a plate with a screen or rake.

Types Of Classifier.pdf

In wet classifiers coarse particles move faster than fine particles at equal density. High density particles move faster than low density particles at equal size. Industrial classification may be carried out in different types of classifiers and these classifiers are normally (i) hydraulic classifiers, (ii) mechanical classifiers, and (iii) cyclones.
