Agitator Bead Mills

Wet-milling technology has been revolutionised by WAB with the development of its horizontal agitator bead mill: It allows very fine particle distributions down to nanometre size to be achieved – with maximum milling efficiency. 
With its world famous DYNO®-MILL, WAB is the undisputed specialist in dispersion and wet-milling technology. 
Our range of machines has the optimum wet-grinding unit for every type of wet-milling task. We cover the specific needs of the pharmaceutical industry, for example, with special designs. Furthermore, we regularly bring new developments to the market. We are therefore expanding the spectrum of wet-milling technologies. 
With grinding chamber volumes from 0.08 to 600 litres and the capability of achieving particle sizes below 50 nanometres, we are your “one-stop shop” for wet-milling technology.


The innovative DYNO®-MILL ECM-AP machines are unsurpassed when it comes to wet milling of suspensions: They offer high grinding efficiency – in both pass mode and circulation mode. They achieve the finest and narrowest particle distributions down to the nanometre range. They also enable especially fast product changes.


The new DYNO®-MILL UBM series is ideal for dispersion and ultra-fine grinding. It processes low to high-viscosity suspensions for a wide range of applications. During development, we placed particular emphasis on durability, ease of maintenance and the best total cost of ownership.

Disc Mills

The original agitator bead mills from WAB are true all-rounders: This type of machine is used in practically all applications – thanks to decades of work in our development department. We adapt the series to meet highly specific customer requirements. It works just as reliably in mass production as it does in dispersing the finest raw materials.

Mills for the pharmaceutical industry

WAB pharma mills are manufactured to the highest quality standards for the pharmaceutical industry. The choice of materials, surface finishes and GMP-compliant design offer reliable production solutions for practical implementation. Metal-free grinding of active pharmaceutical ingredients is a standard option. We adapt the CIP and SIP capable pharma mills to individual customer requirements.

Laboratory Mills

These agitator bead mills have been specially developed for a laboratory environment. They are ideal for developing new formulations with small product quantities and calculating scale-up factors. Each of these laboratory mills can be operated with two grinding principles. This increases flexibility in product development, reduces investment costs and saves valuable floor space in the laboratory.Stellfläche im Labor.

Special Mills

We develop special mills to meet particularly demanding criteria. Their more extreme form broadens their potential for use in precisely defined areas. In certain special applications these agitator bead mills are the only alternative!
