Types of Classifiers in Mineral Processing

In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow. It separates coarse and fine solids, carried

Classification of Materials and Types of Classifiers

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. Basically they all according to the principle that the particles are suspended in water which has a slight upward movement relative to the particles.

The primarily used equipment in crushing are-jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, closed circuited with a classifier unit, are generally employed for grinding purposes in a mineral processing plant. Crushing is a dry process whereas grinding is generally performed wet and hence is more energy

Unlike the others it has no moving parts and is ed in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE.

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

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causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated.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

[PDF] THE SIZING AND SELECTION OF HYDROCYCLONES By

For many years, hydrocyclones, commonly referred to as cyclones, have been extensively utilized in the classification of particles in comminution circuits. The practical range of classification for cyclones is 40 microns to 400 microns, with some remote applications as fine as 5 microns or as coarse as 1000 microns. Cyclones are used in both primary and secondary grinding circuits as well as

Mineral - Classification of minerals | Britannica

Mineral - Mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level

TECHNICAL NOTES 3 Hydraulic Classifiers - Mineral Tech

A characteristic of virtually all practical classifiers is the phenomenon of short circuiting. All classifiers exploit some physical process to separate particles on the basis of size. This will be the differential settling velocity in a viscous fluid in spiral, rake and hydrocyclone classifiers or the physical sieving action in a screening

Spiral separator - Wikipedia

Wet Spiral Separators. Spiral separators of the wet type, also called spiral concentrators, are devs to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties (e.g. drag).The dev consists of a tower, around which is wound a slu, from which slots or channels are placed in the base of the slu to

Cyclonic air classifiers and High efficiency cyclones -

Cyclonic air classifiers and High efficiency cyclones. These high efficiency cyclonic air classifiers take advantage of the principle that particles of different sizes, shapes, or specific gravities can be separated through the use of an upward flow of air creating variations in the ascending vortex.

Hydrocyclone - Wikipedia

A hydrocyclone (often referred to by the shortened form cyclone) is a dev to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance.This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.

Air Classifiers -

This is achieved through the classifiers intelligent airflow design and use of recirculating, secondary airflow. Ancillary air solutions provide the systems required for the correct operation of the classifier equipment, as well as, offering other dry solution capabilities.

Elutriation - Wikipedia

Elutriation is a process for separating particles based on their size, shape and density, using a stream of gas or liquid flowing in a direction usually opposite to the direction of sedimentation. This method is mainly used for particles smaller than 1 μm. The smaller or lighter particles rise to the top (overflow) because their terminal sedimentation velocities are lower than the velocity of

An air classifier is an industrial machine which separates materials by a combination of size, shape, and density.. It s by injecting the material stream to be sorted into a chamber which contains a column of rising air.Inside the separation chamber, air drag on the objects supplies an upward force which counteracts the force of gravity and lifts the material to be sorted up into the air.
