types of classifiers in mineral processing

May 26, 2016 · Rake Classifier. The Rake Classifier is designed for either open or closed circuit operation. It is made in two types, type “C” for light duty and type “D” for heavy duty. The mechanism and tank of both units are of sturdiest construction to meet the need for 24 hour a …

classification - sciencedirect

Jan 01, 2016 · Rake Classifiers. When rakes are used in place of spirals, the classifiers are called Rake classifiers. These are less common than spiral classifiers. The rakes consist of one or more parallel lines of steel plates that hang from a central shaft or shafts. The plates are hinged onto these shafts and have a reciprocating movement

classification of materials and types of classifiers

Oct 31, 2015 · Rake classifiers are also used for close circuit grinding. Both rake and spiral classifiers are more efficient in classifying the coarse particles. But they are very costly for installation. In these classifiers the separation achieved is distinct. Dry classifiers. Dry classifiers are based on the principle that separation by air fluidization

what should you know before choosing spiral classifier?

Nov 07, 2018 · With the development of classification operation, rake classifier is already replaced by spiral classifier for complicated structure and weak classification effect. Tank classifier is gradually replaced by hydrocyclone for large …

separators, classifiers, and screeners selection guide

Rake classifiers lift solid-liquid mixtures up onto a plate with a screen or rake. Spiral classifiers use an Archimedes pump screw to lift solid-liquid mixtures up onto a screen for dewatering. Bowl classifiers, bowl desilters, hydroseparators or countercurrent classifiers are other types or mechanical classifiers

explain in brief rake and spiral classifier Common classifiers of the type include he simple gravitational devices used in wet Fig 79 Diagram of rake classifier grinding circuits, such as spiral and rake classifiers see Fig. 19, and centrifugal force devices such as the cyclone and vane classifiers see Fig. 20ir Spiral and rake classifiers work on the principle that the slower

lime slacker classifier - ekcp

The classifier section utilizes Rake Classifier, similar to that which has been successfully used in the metallurgical industry for many years. Virtually all of the plus 65 mesh inert solids are removed in this compartment. The grit is sprayed with water at the top of the screw to recover any remaining soda values before discharge

classifier - an overview | sciencedirect topics

The unit drags coarse sandy sediment from the settled feed pulp by a continuously revolving spiral along the bottom of an inclined surface to a higher discharge point at one end of the settling tank (Fig. 13.23). The fines overflow at the other end. The rake classifier is a variation in the mechanism of shifting the coarser component. The rakes dip into the feed pulp, move in an …

rake classifier - bowl rake classifier, dewatering classifier

A bowl and rake classifier is typically used to separate coarse and fine particles of granular material temporarily suspended in water. The coarse particles settle to the bottom of the vessel and are scraped by a set of blades. The fine particles are carried over the edge of the classifier. This is how the offered rake classifier works

rake classifier tuke and bell ltd

Typically the Rake Classifier is used in conjunction with a Crossflow type Grit Detritor and together carries out the complete grit extraction process within a compact area. The system can be located either above or below ground level. The Rake Classifier is available as a design suitable for a civil or steel chamber construction

three factors that affect classifying efficiency-xinhai

Dec 12, 2017 · Spiral classifier plays a significant role in various mineral processing equipment. It can be said that spiral classifier is an indispensable part of the mineral processing. Here we introduce three factors that influence the working efficiency of the spiral classifier. Ⅰ. Equipment Structure. 1. Classifying area size

spiral classifier

Spiral Classifier. Spiral Classifier is a traditional type of classification equipment, mainly for metal mineral processing for the slurry density and particle size on the wet grade, mining operations could also be used in the flow desliming. Model: Submerged series and High Weir series. Spiral Diameter: 300-3000mm. Sink Length: 3000-14300mm

classifiers - solidswiki

The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated; the settled material is thus slowly moved up the incline to the discharge. In the duplex type one set of rakes is moving up, while the other set returns. Spiral classifiers. This classifier uses a continuously revolving spiral to move the sands up the

spiral classifier - ekcp

EIMCO-K.C.P. Spiral Classifiers is art of separating the solid particles in a mixture of solids and liquid into fractions according to particle size or density by methods other than screening. In general, the products resulting are (1) a partially drained fraction containing the coarse material (called the underflow) and (2) a fine fraction along with the remaining portion of the liquid …
