Principle Of Operation:

• The material to be ground is conveyed from a hopper by screw feeder or pneumatically fed through Rotary Air Lock Feeder to the grinding chamber of the Air Classifying Mill (ACM). The pins/bars of the rotor break the particles of the material. These particles are entrained by an air stream which enters below the pin rotor and are carried up between the inner wall and the shroud ring with baffles which decrease the air swirl. These particle then enter the classifying section where the fine material is carried out with the air through the classifier rotor to the outlet, the course material is thrown against the shroud rind and carried down to the pin rotor for further reduction. After leaving the micron air mixed with fine particles enter the bag filter where the fine particles are separated and the clean air is discharged to the atmosphere.
