Rotating wheel air classifiers have been around for several decades although a number of design improvements have taken place. Rumpf and co-workers [2], [3] led the early work on air classifiers and introduced new ideas such as spiral classifiers with rotating walls and recycling of the coarse fraction.

Centrifugal Classifiers Gravitational Industrial Classifiers These units employ centrifugal forces, similar to cyclones, to separate particles at cut points between 20 and 100 microns. A series of internal baffles apply drag forces to the coarse particles while allowing air to pass through them, resulting in separation of the fines.

cost and less space required have caused operation with spiral classifiers to becomerestricted. The application range ofspiral classifiers range is 0.070 to 1 mm, depending on the material to be separated. Compared to cyclones, spiral classifiers cover a coarser separation range. Autogenous cyclones also cover a coarser range, replacing

Spiral Classifier. Spiral classifier is used for material classification with spirals used to stir and convey materials according to the difference in material settling velocities. It is a kind of gravitational and hydraulic classifiers. The specification of spiral classifiers is represented by the number and diameter of spirals.

Air classifiers use the spiral air flow action or acceleration within a chamber to separate or classify solid particles. Powders suspended in air or gas enter the cyclone and the heavier particles spiral out and down where they are collected. The air and finer particles flow up to the top where they may be passed to another cyclone with finer ...
