Air Classifier

 · 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. Due to the dependence of air drag on object size and shape, the objects in the moving air column are sorted vertically and can be separated in this manner.

Factors Affecting Air Classifier Efficiency

 · This is an advantage of the new classifier compared to gravity fed classifiers. Moisture levels below 0.5% usually do not cause a problem. Dry grinding generates friction heat in the mill, which reduces the moisture level. Of course, care must be taken to avoid condensation in the classifier and conveying system at start-up from cold temperatures.

Air Classifiers

An air classifier is an industrial machine which sorts materials by a combination of size, shape, and density. 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.

Air classifiers

Gravitational air classifiers. With the use of air flow, gravity and sharp directional changes, the gravitational classifiers perform accurate separations of material from 1,700+ microns down to 150 microns. Coarse particles are conveyed by gravity through a valve at the bottom of the unit, and fine material is conveyed by air to a fabric filter.
