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. The wetting and homogenization of solids in liquids, deagglomeration and dispersion, all the way to true comminution of primary particles make the agitator bead mill a universal wet processing machine.

The roller mill has two cylindrical rolls of stone or metal, mounted horizontally, which are capable of rotating on their longitudinal axes. One roll is rotated directly and the other rotates freely. When material is placed above the rolls it is drawn in through the nip and the second roll is rotated b y friction.

For comminution of finer particle size ranges (20mm > P 80 > 30 μm) machines like the ball mill, vertical roller mill, hammer mill, roller press or high compression roller mill, vibration mill, jet mill and others are used. For yet finer grind sizes (sometimes referred to as "ultrafine grinding"), specialist mills such as the IsaMill are used.

Indeed, there is no alternative to roller mills for fine comminution as part of plastic preparation. Many brickmakers work with raw materials for which a roller gap of roughly 0.8 mm or wider achieves adequate comminution. HÄNDLE's Beta roller mill concept was developed as a cost-effective, state-of-the-art alternative to the Alpha II.
