HEXADUR® - ideal for cement

Köppern's HPGR technology is based on a concept very similar to our traditionally successful roller presses for briquetting and compaction. However, continuous development of innovative wear protection materials since the mid-80’s has paved the way for Köppern’s entry into the cement industry, where they can be used in cement grinding applications as well as raw material grinding. HEXADUR® also demonstrates its excellent wear resistance where slag, or material mixtures containing slag, are being processed.

The adoption of high-pressure grinding throughout the cement industry has already generated enormous savings in energy and wear-material costs (read more). But in many applications, excessive wear of the rolls limits the economical use of HPGRs. In this respect, Köppern's HEXADUR® wear protection system has proved to be an optimal solution for all customers experiencing strong roller wear. And as a universal industry solution, HEXADUR® tires can be fitted to HPGRs of all suppliers.
