Prater MAC Air Classifiers process dry materials to exceptional fineness and uniformity over a wide range of feed variations. Offering separations from 3 to 150 micron, they are ideal for use in closed-circuit with a conventional milling system or as independent …

It was not possible to measure the internal air flow in the machine, as pressure probes would have disrupted the particle stream. However, it was possible to measure the air flow passing the control valves and entering the machine, as shown in Fig. 2.This was accomplished by installing air flow meters in the entry of the air classifier.

Air, free of material, leaves the product collectors and returns to the fan, which generates the airflow through the system. The main air stream returns to the mill discharge area to convey more material to the classifier. At the discharge of the fan, a controlled amount …

An independently controlled, internal air classifier separates off-spec particles, recirculating them back into the grinding chamber for further size reduction. As a result, air classifying mills outperform single-pass impact r mills in their ability to handle …

For concentrated proteins, milled flour is further processed in a dry state by passing it through an air classifier. Air Classifiers are built to efficiently separate smaller protein particles from the other nutrients by utilizing a precisely controlled amount of centrifugal force. The protein particles are then collected separately from the ...
