Technology Center

We invite you into our application technology center to take advantage of our knowledge and experience in the field of grinding and classifying. Dry grinding, air classifying, sieving and milling processes can be tested with your product under process-oriented conditions. Trials ranging from small laboratory scale for your R&D phase to production scale to enable a proper scale up of the production line can be offered.


Experienced process engineers with interdisciplinary knowledge in the field of dry grinding are at your service in our technology center. In consultation with you we will develop tailor made solutions for your product. As a matter of course, all relevant test parameters are recorded during a trial and will be provided to you in a detailed test report.

The services provided include:

  • Laboratory as well as production scale test grinding and classifying with your product
  • Scale up tests
  • Product as well as process development & optimisation
  • Consultation and test grinding to aid the selection of the optimal mill type for your product
  • Rental machines
  • Production of test batches
  • Customer demonstrations
  • Problem solving as well as optimising of existing production lines in our technology center or at your premises


Please don’t hesitate to contact us with your questions or enquiry:        /  Contact us        Trial preparation form


Our technology center is equipped with extensive equipment in order to attain optimal results for a large range of products and applications. Profit from a reliable and flexible plant operation which can be adjusted according to your requirements as well as the possibility to run laboratory or small production scale tests in our technology center.
