differences between rake and spiral classifiers

  • Rake Classifier Mineral Processing & Metallurgy

    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causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated.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.

  • Differences Between Spiral Classifier and Hydrocyclone

    There are two ways to separate the spiral classifier: one is by the number of the spiral axles, which could be classified as the single spiral classifier and double spiral classifier. The other way is by the height of the weir, which could separate as high weir, low weir and submerged.

  • Separators, Classifiers, and Screeners Selection Guide

    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.

  • Spiral Classifier for Mineral Processing

    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

  • Chapter 13 Classification ScienceDirect

    13.2.2. 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.
