Classifiers: Fourth generation classifiers. The evolution of classifiers has hinged on improvement of their cutting ability, with a better sorting of fines and coarse and a lower by-pass, writes Anjani Kumar. The continuous demand of increased strength cement by users has forced cement manufacturers to ensure cement of a higher fineness.

Circulating air classifiersCirculating air classifiers are widely used, mainly in cement industry. One type of such devices produced by Sturtevant [22] (Fig. 5c) consists of two coaxial exterior and interior vessels. Particles entering the device from the top onto the plate are scattered within the interior vessel by a rotating plate.

All dry grinding applications in the cement industry use what is referred to as air separators or classifiers. The simplest form of a separator is a dropout box. By …

The process has been utilized by different industries i.e., cement, food, coal, where water interaction is avoided. Up to date, different types of air classifiers e.g., static and dynamic classifiers, have been developed. Static air classifiers adjust the target product size only by changing the magnitude and the direction of the airflow.

Air classification is a process employed to control or adjust the final product fineness of the grinding circuit where water interaction with the material is avoided. This technology was developed early in the 19th century to meet the demand of cement industry where tube mills with high capacities were employed.
