Classifiers and Air classifiers. Hosokawa Alpine classifiers and air classifiers make everything fine! No matter what fineness you require, our classifiers were developed for a wide range of applications. As a result, …

The air classifier cyclone sorts material by inserting the material into a chamber that has a column of rising air. Air drag on the material supplies an upward force and lifts the material into the air. Since the air drag is dependent on the material's size and shape, the material can be sorted and separated vertically.

Air classifiers separate materials based on shape, size, and density and are most commonly used in an industrial process involving mixed materials that need to be separated quickly. ... Air classification is the most effective and efficient means of separating material from a stream that needs to be sorted or for increasing productivity when it ...

The present study provides theoretical guidance for the structural optimization of an air classifier with a rotor cage. 1. Introduction. An air classifier is a key piece of equipment in the powder preparation process that is widely used in the mineral processing, food processing, and fine chemical indus-tries [1–4].

Air classifier working principles involve airflow, classifier aperture, feed rate to air ratio, classifier wheel speed, and size and quantity of classifier blades. A fan generates air velocity and controls the drag force on particles entering this classification zone. Lower airflows permit only finer particles to go through the rejector cage ...

Air classifiers are available for laboratory applications requiring only a few pounds per hour feed rate, all the way up to large industrial capacities of 500 tph or more. Air classifiers are often used in closed circuit with …

Air classifiers eliminate the blinding and breakage issues associated with screens. They work by balancing the physical principles of centrifugal force, drag force, collision and gravity to generate a high-precision method of classifying particles according to size and density. For dry materials of 100-mesh and smaller, air classification provides …

Our three-fraction air classifier The NESTRO three-fraction separator NDFS 14, which generates a pure PET fraction, transports the material to be classified to the classifier housing via an acceleration conveyor with controllable belt speed. A targeted air flow spreads the discharge parabola of the sorted material.

Modern classifiers accomplish each of these requirements by optimised feed systems, dispersion zones to separate the particles, and designed particle …

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.
