The Svedala Gyrotor, a rotating vane air classifier, separates dry solid particles by size and is ideal for any separation where the fines are 35 mesh or finer. 

Products of 99.9 percent passing 325 mesh with an average particle size of 5 microns or finer are obtainable for ultra fine applications. 

When used in connection with a grinding mill, this classifier system controls product size; improves energy efficiency of the grinding mill; and provides a transport system for the ground material. 

These classifiers handle feed rates from 0.1 to 200 tons per hour depending upon the desired cut point and material density.
