The invention relates to an air classifier for classifying granular material in three fractions. In order to obtain fine and coarse goods with this multi-stage sifting, each of which has a narrow grain spectrum, i.e. the individual siftings are carried out with a very sharp separation, in the transition area from the first sighting stage to the second, underneath …

In order to classify granular material into at least three fractions, previously bar basket classifiers with at least two classifier wheels have been used which are arranged in a housing spaced one on top of the other. The classifier wheels arranged one on top of the other were provided here with separate lines for feeding in the classifying air and …

As the important air classification equipment, turbo air classifier is widely used in a variety of fields, such as building materials, chemical industry, food and medical industry, etc. [1], [2].With the rapid development of materials science, higher demand for classification efficiency and accuracy has been raised [3].For air …

This paper presents a study of the use of flow baffles inside a centrifugal air classifier. An air classifier belongs to the most widely used classification devices in mills in the mineral industry, which is why there is a great interest in optimizing the process flow and pressure loss. Using Computational Fluid Dynamics (CFD), the flow profile in a classifier …

Static air classifiers achieve accurate separations from 12 mesh size (1.4 mm) to 20 (micrometer). The static air classifiers are designed to achieve extremely accurate separations even though they contain no moving elements in the airstream. This is achieved through airflow design and use of recirculating, secondary airflow on finer ...

The classifier's focus: its classification effect. An air classifier divides material flow into two parts. One of them consists of fine material, the other one of coarser parts. Centrifugal, gravitational and flow forces impact on mass elements which are of di"erent sizes and use natural laws to bring about classification.

FIELD: processes of separation of granular materials according to the size by ascending current of air, applicable for fractionation of granular materials in mining, chemical, grain processing, food, building and other branches of industry.

Material discharging from the mill is air conveyed vertically into the bottom of the classifier through a multivaned rotor mounted on a vertical shaft. As the mixture travels upward through the classifying section, it is subjected to centrifugal forces induced by a vaned rotating element. The speed of the rotating element controls the product size.

Key Benefits. 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.
