Let me describe a cycle of the Rake Classifier arm to you. The arm, with a series of rakes along its length, drops into the flow of slurry and is pulled upwards. Some of the fine material will flow over, the top of the rake. The rest will be pulled along with the coarser heavier material up the incline. When the arm reaches the end of its throw it will lift the rake out of slurry allowing the ...

19-08-2015· A rake classifier is a rectangular classifier tank with an inclined channel, and equipped with a reciprocating raking mechanism which transports the settled solids towards the upper discharge end.

rake classifier. Rake Classifier - Metallurgist & Mineral Processing Engineer. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.

A rake classifier comprising a tank having side and end walls, a rake structure, an electric motor having a motor shaft and motor-driven means for imparting raking movement to said rake structure, said rake structure positioned in said tank and having two pairs of upstanding hanger elements spaced along the length of said rake structure, said motor driven means comprising a driven slot in each ...

01-01-2016· 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.

Early rake classifiers are shown in U.S. Pat. Nos. 849,379 to J. Van N. Dorr; 1,024,647 to D. J. Nevill; and 1,156,543 to D. J. Nevill. SUMMARY OF THE INVENTION. In accordance with the invention, a rake classifier having improved motor-driven means for imparting reciprocating movement to the rake structure is provided.

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 The Tuke & Bell Rake Classifier is a multiple-rake reciprocating mechanism, mounted within a cleaning channel, which is a narrow, continuously sloping ramp. The reciprocating action moves the grit, up the ramp towards a discharge point above top water level.

The grit rake classifier lifts the grit out of the chamber for disposal. Our grit rake classifiers can be manufactured from a range of materials including steel box section or angle iron. The grit rake is welded together, shot blasted and cleaned.

The patented REFLUX® Classifier is one of our most advanced fine particle, gravity-based separators, offering significant advantages in capacity, adaptability and efficiency. Incorporating the new “laminar high-shear-rate” mechanism, along with other advancements, our REFLUX Classifiers …

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.

Spiral classifier is mainly composed of the driving device, the spiral body, the groove body, the lifting mechanism, the lower seat and discharge valve. The machine base adopts channel steel, the body adopts welded steel plate. Screw shaft parts use the pig iron, and wear resistance. Working Principle:

In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn’t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do. As it is revolved in the slurry the spiral is constantly moving the coarse backwards the fine material ...

Basically the different wet classifiers are g ravity settling tank, cone classifier, double cone class ifier, hydrocyclone classifier, spiral classifier, and rake classifier. 3.2 Gravity settling tank
