The adoption of high-pressure grinding technology over the last 25 years has led to significant energy savings as well as reduced costs for wear material. But the conventional welded rolls used predominantly today in high-pressure grinding roller presses (HPGRs) are subject to rapid and excessive wear. Depending on the abrasiveness of the feed material, hardfaced rolls need to be refurbished at more or less short intervals. They tend to become “softer” with repeated welding of the hardfacing, resulting in i
• constantly decreasing grinding efficiency • cost-intensive plant downtime • frequent maintenance and repair • shorter replacement or refurbishment intervals. While welded rolls do of course benefit from attractive initial pricing, their running costs make them increasingly uneconomical over time. Köppern responded to this challenge during the early 90’s by developing the innovative and unique HEXADUR ® wear protection system. Our HEXADUR ® tires for HPGRs feature an extremely wear-resistant su
