Alpine Ventoplex Classifier

The Ventoplex classifier type C is an internal recirculation classifier designed for high fines yields at low energy consumption. Fineness can be simply changed between D97 = 24 microns and 200 microns. Up to size C25V, the product is fed to the center of the classifier head via a hollow shaft, from which the material falls onto a centrifugal plate underneath the classifying wheel. The centrifugal plate distributes the feed material uniformly in the classifying chamber. Coarse particles fall against the upward flow of classifying air to the bottom, collect in the coarse material cone, and are discharged through the side of the machine via a gravity chute. Fine particles in the feed material become entrained in the upward flow of classifying air and enter the classifying wheel along with the classifying air.


The particles in the classifying wheel are classified by the two competing forces, namely centrifugal force, whereas for the fine particles, the drag force of the air flow predominates, allowing the particles to pass through the classifying wheel. The Ventoplex air classifier requires no additional external dust collector to separate the fines.
