We are offering air classifiers. air classifiers balance the physical principles of centrifugal force, drag force and gravity to generate a high-precision method of classifying particles according to size or density. For dry materials of 100 mesh and smaller, air classification provides the most effective and efficient means for separating a product from a feed stream for dedusting, or for increasing productivity when used in conjunction with grinding equipment, as well as time- and energy-saving advantages. dinammic seperators dynamic separator for a grinding mill having a stator installed in a stationary manner and a rotor provided on a rotary shaft such that it faces the stator. Between the stator and the rotor is provided a small gap for the passage of processed material in order to separate and discharge the processed material from the dispersion media. The rotor is arranged and configured together with the stator such that the relative position of the rotor rim area and the stator are constantly varied.
