AIR CLASSIFIERS - Van Tongeren

Air Classifier Systems. Van Tongeren developed three models of air classifier in 1958, using knowledge of air flow gained through the earlier development of cyclones. The equipment is used to classify particles into different size ranges (as opposed to a cyclone, which is designed to collect particles of all sizes).

Example air classifier mill system Figure 3 shows a vertical air classifier mill installed in a closed-loop system. The system uses an inert gas, nitro-gen, rather than air to safely handle a potentially explosive material, and its closed-loop design allows the expensive inert gas to be recycled through the mill. (The closed-loop

Air Classifier - WOLFF GROUP

Air Classifiers – Application. Air classifiers are mainly used to separate mineral materials into two phrases. Their task usually consists in separating the finest dust (e.g. fillers, quartz sand) from the final product, as the dust worsens the physiochemical properties of the product, or separating the finest fraction which is the final product (e.g. toners).

AIR CLASSIFIER TURBO CLASSIFIER - AAAmachine

Classifier, revolution speed of the classifica-tion rotor and flow rate of the passing air are adjusted. Since the variable range of the air flow is limited, it is usually maintained at certain level to be used for fine adjustment. Therefore, the number of revolution of the classification rotor is mainly used for the ad-justment. Air flow
