How does an air classifier work?

How does an air classifier work?

It works 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.

What is the principle of classifier?

Usually the principle of the classification is based upon the various densities, specific gravity, terminal falling velocities of particles in liquid and in air.

What is a Sturtevant air classifier?

Sturtevant air classifiers balance the physical principles of centrifugal force, drag force and gravity to generate a high-precision method of classifying particles according to size or density. All three Sturtevant air classifiers offer durable construction, as well as time- and energy-saving advantages.

What is classifier in mechanical operation?

Classification is a process of dividing a particle-laden gas stream into two, ideally at a particular particle size, known as the cut size. An important industrial application of classifiers is to reduce overgrinding in a mill by separating the grinding zone output into fine and coarse fractions.

How an air classifier works in a waste recycling plant?

Air classifiers for recycling separate particles of different densities using an air flow and the relationship between the force of inertia and/or gravity and the drag. The machines are used in the recycling industry and paper processing.

What is a mechanical classifier?

[mi′kan·ə·kəl ′klas·ə‚fī·ər] (mechanical engineering) Any of various machines that are commonly used to classify mixtures of particles of different sizes, and sometimes of different specific gravities; the Dorr classifier is an example.

What is classifier and clarifier?

A settler that removes virtually all the particles from a liquid is known as a clarifier, whereas a device that separates the solids into two fractions is called a classifier.

What is hydraulic classifier?

Tank into which ore pulp is fed steadily and subjected to the sorting effect of a stream of hydraulic water that rises at controlled rate. Heavier or coarser equal settling particles gravitate down and away via a bottom discharge, while lighter ones are carried up and out.

What do you mean by air classification?

Air classification is the process in which fine particles are separated by utilizing the opposing forces of centrifugal force and aerodynamic drag. An air classifier can precisely, predictably, and efficiently sort particles by mass, resulting in a coarse particle fraction and a fine particle fraction.

What is the difference between clarifier and classifier?

Answer: A settler that removes virtually all the particles from a liquid is known as a clarifier.  whereas a device that separates the solids into two fractions is called a classifier.

What is a classifier in mining?

Classifiers help to achieve optimum size control, improved product quality, enhanced efficiency and increased throughput. They can be used in mining operations as well as in aggregates and manufactured sand production.

What is classifier in mineral processing?

Classification, as defined by Heiskanen, is a method of separating mixtures of minerals into two or more products on the basis of the velocity with which the particles fall through a fluid medium. The carrying fluid can be a liquid or a gas.
