In many cement plants worldwide, our high-pressure grinding roll is a proven, reliable and energy-saving solution for raw material and cement grinding. First sold in 1986, over 95 % of all polycom® mills ever built are still in operation today. However, after several decades of production, some of these mills no longer develop their full performance, which leads not only to reduced throughput but also to increased specific energy consumption. How can the full performance be achieved again?

In the spare and wear parts business, we focus on shortening the unscheduled downtimes of our customers‘ plants and improving plant performance.

To achieve this, our team of experts examines the individual production processes and based on their OEM expertise and new material technologies, develops suitable wear part solutions for the respective application in combination with appropriate business models.

Thanks to our long-term experience as an OEM supplier, we can provide innovative spare parts concepts to meet your quality and performance requirements: on the one hand, the engineering and manufacturing of individual spare parts in line with your requirements; on the other hand, the ongoing development and enhancement of spare parts and components to increase the availability and performance of your plant. We also offer spare and wear parts for plants that were engineered and erected by third parties.
