Willy A. Bachofen AG Maschinenfabrik

Willy A. Bachofen AG provides equipments for the dry mixing and wet milling.

DYNO®-MILL, TURBULA® or dyna-MIX® are all worldwide recognised brand names.

With R&D and a production facility under the same roof at its headquarters in Basel / Muttenz (Switzerland), WAB offers the pharmaceutical industry innovative concepts and advanced processes which constantly set new standards.

Fine dispersion and grinding technology

For decades, WAB has been the undisputed specialist in dispersion and wet milling technology with its renowned DYNO®-MILL. This agitator bead mill allows the particle size reduction (or comminution) through a mechanical breakdown of the solids. It is used to create particles of a determined distribution profile, and for instance, increase the solid content surface area. Dispersion and wet fine grinding of pumpable products (with low to high viscosity), with size ranges from 500um down to 50 nanometer can be achieved in a completely enclosed system.

Three-dimensional mixing technology

The concept of the patented dyna-MIX shaker-mixer is based on its controlled three-dimensional movements. The cinematic principle ensure a gentle, constant and reproducible mixing process all along the process.

Solid Partnership

We work in co-operation with customers, over decades, who entrust to us new challenges and process investigations. Thus, running trials at WAB allows the adequate process parameter settings for existing products to achieve the maximum production efficiency.

Homogeneity of dry form mixtures is capital and any kind of compromise in regards to productivity, appearance and quality of customers product is excluded.

High process performances and specific solutions are demanded especially concerning the reproducibility of mixing results which remains the key validation parameter. The three-dimensional shaker-mixers of the dyna-MIX® series fully meet these requirements. In most challenging requirements sometimes the dyna-MIX® even represents the only solution.Thanks to its flexibility and the quality of its execution, the blending…

DYNO®-MILL for Production Purpose

The compact milling chambers of the DYNO®-MILL ECM-AP series in combination with the powerfull turbulences generated by the DYNO® Accelerators provide exeptional cleanability.

Available in two, ten, 20, or 60 litres chamber volume, the DYNO®-MILL of the ECM-AP series is equipped with the unique dynamic separation system, allowing the use of grinding beads down to 0.1mm.The use of product contacting parts made of zirconium oxide offers the necessary wear-resistance and fulfils the GMP requirements entirely.The WAB VIEW Programmable…

DYNO®-MILL for Laboratory Purpose

DYNO®-MILL RESEARCH LAB with its compact size is the perfect device for wet milling feasability studies, especialy when only a limited amount of active pharmaceutical ingredient is available for testing.

Batch starting from 100ml only need a few grams of solids to be processed. After the grinding process the milling chamber is quickly disassembled from the drive module for easy cleaning. All product contacting parts can be sterilised.DYNO®-MILL ECM-AP 05 follows the same principle regarding the agitation of the beads, and with its 0,5l. chamber…

Support and Services

WAB AG has its own test facility in a thoroughly modern building, including all the latest analytical testing equipment, with various mills in different sizes, ranging from laboratory up to full production scale.

The partnership with our customers is one of the main aspects for us.


The TURBULA® shaker-mixer is used for the homogeneous mixing of powdery substances.

Even differing specific weights and particle sizes are mastered by this mixing technic thanks its unique rotational, inversional and translational movement combination. The product is mixed in its own closed container. Therefore, the production process can be run dust-free under c'GMPs conditions.Three types of machine sizes belong to the TURBULA® series: T2B (max. 2 l.),…

Wet Milling and Dispersion – From Micron down to Nano

Wet milling by agitated small beads (media) allows the most efficient grinding of wet forms to the low micrometre range – even the low nano range – with narrow particle size distribution.

The ever-increasing demands of our customers requires solutions with the lowest life cycle costs, while technical challenges are constantly evolving.Therefore, only equipments and components with the highest material quality and the best abrasion resistance can answer today's performance needs.WAB's patented DYNO® Accelerators represents the heart of the DYNO®-MILL ECM series. These agitators generate an incomparable…
