This newest fine classifier was conceived to combine with an upstream mill. The direct integration of the InlineStar classifier behind a mill creates a continuous grinding/classifying plant that reduces the number of required plant components. Available for separation limits from 2.5 to 60 µm (d97).

CM1 is a ball mill in closed circuit with a high efficiency classifier and a pregrinding system. CM2 is an open circuit ball mill system. The product from CM1 and CM2 are 4700 and 4100 Blaine respectively. To satisfy the strength requirements of the cement, the cement mill feeds for CM1 and CM2 included 68% and 79% clinker, respectively.
Rotary airlock valve capacity calculations use the following formula: C = R ÷ D ÷ E ÷ S. Fill factor is normally stated at 80% for average conditions but can be adjusted to between 65% and 95% depending on product flowability and pressure differential across the airlock. In general, good flowing products will fill more and sluggish ones less.
and the air sweep passes all the way through an integral rotating classifier. After the last feed input the central to the mill table, due to mill and roller's relative movement, materials get into the grinding layer between the roller and the mill. In suspension between classifier and table, material drying transpires will takes place.
Measuring and optimizing air classifier performance Ivan V. Klumpar Badger Engineers, Cambridge, MA, USA Operation of air classifiers, particularly in closed circuit with grinding mills, is described. Performance measures are reviewed and an improvement of the AIChE standard method of calculating the selectivity curve is proposed.
The classifier's focus: its classification effect. An air classifier divides material flow into two parts. One of them consists of fine material, the other one of coarser parts. Centrifugal, gravitational and flow forces impact on mass elements which are of di"erent sizes and use natural laws to bring about classification.
A dynamic air classifier equipped with a rotor (the rotating part) driven by a separate motor and stationary guide vanes classifies discharged powder from a mill into a fine product stream (final product) and a coarse reject stream. The classification area of an air classifier is the space between the rotor cage and the guide vanes.

Gyrotor air classifiers, or rotating vane air classifiers, separate dry solid particles by size. They are designed for any separation where the fines are 500 microns (35 mesh) of finer. They can handle feed rates from 0.1 to 200 tons per hour depending upon the desired cut point and material density.
