Grinding with high-quality plant technology

Depending on the product and industry, different demands are placed on the grinding of solids. These requirements can only be met by modern, high-quality, and well-maintained plants. Our customers benefit from a wide variety of plants and different plant sizes, so that implementations ranging from pilots to the production of large orders are possible. We stand by your side as a reliable partner throughout the entire process. We offer plant technology in the fields of micronizing, grinding and cold milling, as well as in mixing, filling, and packaging.

Fine grinding and micronization

Fine grinding and mirconization entail grinding down to the finest particle size and with the greatest possible. In the pharmaceutical sector in particular, the requirements are high - and ACU is able to meet them. We have been a contract micronizer in the pharmaceutical sector since 1999. In our ultra-fine grinding, we achieve a fineness of less than 100 μm. Thanks to our extensive plant technologies, we can use various grinding processes and thus optimally adapt to the product properties of the starting material. Micronization often has a positive impact on the properties of the starting material and, in the pharmaceutical sector, increases its solubility and bioavailability, for example. Our pharmaceutical customers particularly appreciate this in the case of excipients, minerals and vitamins.

Areas of application and experience

Our strength lies in our expertise in many industries and our specialization in life science and pharmaceuticals since the company was founded. We are also happy to support and supply customers in the cosmetics and chemical industries.
