Low velocity air enters the classifier through the front inlet and is drawn through ...
Air Classifiers are industrial machines which are used to separate materials by size, shape, and density. By using forces - such as air drag, gravity and centrifugal force - they sort fine particles from coarse particles and lighter particles from heavier ones. While density does play a role, the air classifier separation process is mainly ...
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.
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.
Details. Pressure Gravity Separators have an international reputation for being the most effective gravities in the industry. Precision control of air-flow, speed of vibration and differential action of the deck ensures excellent gradation and separation.
