Wet batch grinding of alumina hydrate in a stirred bead mill

Experimental investigations on the wet batch comminution of an alumina hydrate in a stirred bead mill are presented. The influence of some operating parameters (mass solids concentration, initial size of particles, stirrer speed and beads size) on both the specific energy and the size distribution of the ground product is discussed.

Solutions in the field of Wet Grinding

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.
