  • Spiral Classifier - EKCP

    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.

    6. TYPES OF CLASSIFIERS Based on their separation principles classifiers are classified into two types Wet classification Mechanical classifiers Spiral classifiers Hydraulic classifier Hydro cyclone classifiers Dry classification Gravitational classifiers Gravitational inertial classifiers Centrifugal classifiers. 7.


  • How Centrifugal Forces Applies to Gravitational Classifiers

    Sharpness of classification is indicated by efficiency of separation calculated from a formula by Taggart. Efficiencies ranged from 76.9 to 84.6 pct, which is generally considered high compared with efficiencies for gravitational classifiers. Effect of Feed Solids Concentration and Type of Underflow Discharge: Three runs, reported in Table III ...


  • A Guide to the Proper Application of Classifiers

    Hydraulic classifiers of the sizer and super-sorter types, Figs. 7 and 8, are narrow, deep, rectangular tanks divided by vertical baffles into a series of pockets. Hydraulic water is added near the bottom of each pocket. Perforated constriction plates, spiral flow arrangements, or jets are used to disseminate the water under pressure (hydrau...


  • Enhanced gravity particle classifier: Experiments with 3D ...

    The concept is initially validated through computational fluid dynamics (CFD) simulations. Preferential movement of coarser particles, which experience greater centrifugal force, to the outer periphery was observed. These predictions are validated by conducting experiments on a 3D printed spiral classifier.

  • Classification - ScienceDirect

    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.

    Spiral-Screw Classifier Capacity Table Hydraulic Classifier Hydraulic Classifier is designed for use in gravity concentration mills for pre¬paring a classified feed for table concentration. The classifier compartments are provided with glass sides so that the conditions existing in each chamber can readily be observed.


  • V. CLASSIFICATION

    Classifiers are divided mainly into two broad classes depending on the direction of flow of the carrying current. Horizontal current classifiers such as mechanical classifiers, spiral classifiers, rake classifiers are essentially of the free settling type. Vertical current or hydraulic classifiers such as elutriators, hydrocyclones, hydrosizers ...


  • HYDROCYCLONES

    The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation. The flow pattern in a hydrocyclone ...

    Effective solids separation solutions for a better bottom line. Throughout the mineral recovery process, operators are looking for ways to improve their performance and drive down costs. Efficient materials separation is part of this puzzle. From hydrocyclones and centrifuges to classifiers, heavy media separation and concentrators, we provide ...


  • Mechanical Centrifugal Air Classifiers - Chemical Engineering

    Mechanical centrifugal air classifiers are used extensively to process aggregates, ceramics, chemicals, foods, minerals, metals, plastics, flyash and other materials. They are normally employed when the particle size that you need to separate is too fine to screen.


  • Air Classifier Equipment for Precision Applications

    Prater Air Classifiers are designed to provide ultra-fine separation and narrow particle distributions for dry bulk materials. Our air classifiers offer size separations in the range of 3 to 150 microns. They are ideal as a stand-alone process that includes a feeder and dedicated dust collection system.


  • How Centrifugal Forces Applies to Gravitational Classifiers

    The peripheral weir receives fluid from the outer radius of the free vortex. This radius possesses the lowest centrifugal force of the outer spiral wherein all separation must be achieved. Consequently, the higher diameter of separation is not surprising. However, the free vortex pattern is also distorted by such a weir discharge.

    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. Trommels are large rotary drum shaped with a grate-like surface with large openings.
