Proven wear protection concepts for long service life in mining processes.

Determined to Build Robust Components for Harsh Environments

Mining processes and the extraction of minerals can be extremely challenging due to complex geoplogical structures, varying mineral deposits and ultimately its harsh environment. Therefore, process euqipment must not only comply with strict safety requirements but also be suitable for operations under demanding conditions. In parallel, a robust design based on resilient materials are crucial to ensure longevity of any equipment as it is in constant contact with highly abrasive materials. When it comes to mining and minerals, rotary and diverter valves are usually installed to control the flow of bulk materials and regulate the discharge of e.g. sand, cement or lime, from hoppers or silos. In addition, they contribute to dust prevention and provide effective sealing against leakage of the bulk material. Coperion components have a long history in the minerals industry. They meet all of the above mentioned challenges with innovative design and proven wear protection concepts which were developed based on results of comprehensive studies. With our in-house test center we are able to simulate various abrasion conditions and define the right measures for your application.

Your challenge is our motivation

Convincing Wear-Protection Concepts

Coperion rotary and diverter valves are carefully egineered and feature wear protection by design. For additional protection, we offer the innovative DUROPROTECT concept which is adapted to Mohs' hardness of bulk material relative to typical bulk makterial's wear characteristics. This wear resistance concept is available in 5 levels.

Minerals Applications

Cement manufacturing involves handling abrasive bulk materials like clinker, gypsum, and raw meal under high temperatures and dust loads. Rotary valves ensure consistent, controlled feeding into mills, kilns, and bagging lines, while maintaining pressure and minimizing leakage. Diverter valves enable efficient switching between silos, conveyors, and processing lines. Their rugged construction is essential for long-term reliability in harsh cement plant environments.

Limestone processing, whether for construction, agriculture, or industrial use, requires precise control of dusty and abrasive materials. Rotary valves manage the steady flow of crushed or powdered limestone into crushers, classifiers, and kilns. Diverter valves allow smooth material routing between storage, screening, and conveying systems. Designed to withstand heavy wear, these valves help ensure process continuity and dust control in limestone handling.

In coal-fired and biomass power plants, material handling is critical to efficient energy generation. Rotary valves control the feeding of fuels like pulverized coal or biomass into boilers and maintain airlock integrity under pressure. Diverter valves allow flexible distribution of materials to silos, burners, or ash handling systems. Withstanding high temperatures, abrasion, and corrosive dust, these valves are vital for reliable, safe plant operation.

Coperion’s wear-protected rotary valves have been a game-changer. We cut energy use by over 95%, saving more than €100,000 annually, with a payback in just nine months. Downtime and costs dropped significantly, and after 20,000 hours, there’s still no sign of wear. We quickly ordered a second valve for another system.
