Introduction:

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.

Service

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 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
  • Trainings??? (for operators, …)
