Tests under real conditions in our Test Center
Innovative solutions aren’t created at a desk – they’re developed through the interaction of theory and practice. That’s exactly what the JOEST Test Center in Dülmen is for. Here, customers can test their bulk materials under near-real conditions and develop or optimize process engineering solutions with precision.
Covering more than 800 square meters, the Test Center houses over 100 machines and test systems – from screening and conveying equipment to drying, cooling, and sorting technologies. This wide range allows for precise testing of the most diverse tasks. Whether fine powders, pasty materials, or coarse bulk solids – the Test Center provides ideal conditions for analyzing materials under real-world conditions and developing tailored solutions.
Especially for complex requirements or sensitive materials, our Test Center delivers clarity: What works in practice? What is the right machine configuration? How can throughput be increased without compromising quality? We answer these questions together – based on real test results.
