Grinding Mill Types, Construction, and Usage Grinding Mills

Fine grinding media inside the mill are agitated or rotated by a stirrer, which typically comprises a central shaft to which is attached pins or discs of various designs. Stirred mills find appliion in fine (1540 microns) and ultrafine (<15 microns) grinding. Most common stirred mills are: Tower mills (VertiMill): In a tower mill,
