Our Product Portfolio

Köppern is a modern, high-tech German company at the forefront of plant supply and machinery manufacturing for various processes related to the fertilizer, cement, minerals and metalworking industries:

  • Briquetting - cold and hot briquetting predominantly for metallurgical applications
  • Compaction - for the production of fertilizers
  • Comminution - high-pressure grinding for the cement industry including air classifiers especially developed for roller press applications as well as high-pressure grinding for size reduction in the ores and minerals industries

Additionally we would like to highlight our highly innovative Wear Protection systems. First introduced in 1996 under the HEXADUR® brand and continuously developed since then, these solutions provide optimal wear protection for high-pressure grinding rollers (HPGRs).

This section is rounded off with a short description of the most important elements and advantages of our range of roller presses.
