Horizontal Disc Mill

Horizontale Scheibenmühle


With the DYNO®-MILL KD, WAB has launched the first horizontal agitator bead mill on the market. The original agitator bead mills from WAB are true all-rounders. This type of machine has been used for decades in practically all applications. The consistently growing range of materials, the material quality, and the adaptation of these models as needed to highly specialized customer requirements make this type of mill the first choice in many applications today. The DYNO®-MILL KD disc mills are available with grinding chamber volumes from 0.15 to 600 litres and are suitable for practically all types of grinding media. The production mills can be operated with grinding bead diameters from 0.5 to 2.5 mm.


In the horizontal grinding chamber, the specially designed DYNO® agitator discs are mounted symmetrically on the agitator shaft. They transfer the kinetic energy required for the grinding operation to the grinding beads.
With the correct process parameters, these disc mills achieve outstanding grinding results still today, especially in pass mode operation.
The specific design of the individual machine models depends on the grinding chamber volume. The models DYNO®-MILL KD 20 to DYNO®-MILL KD 60 are optionally available with a dynamic gap separator or a screen separation system.
