Agitator bead mills are grinding machines for ultra-fine processing of solids in liquids. Their area of application covers the particle size range from 200 μm (max. 500 μm) down to the submicron (nanometer) range. With a comminution factor down to 1 : 10 000 (200 μm --> 20 nm), the application range is extensive and the variety of tasks extremely diverse.
