Cement grinding is where efficiency is either unlocked or silently lost. As the final and most energy-intensive step in cement production, cement grinding has a decisive impact on power consumption, product quality, plant availability and overall operating costs. Even small inefficiencies in the grinding circuit are multiplied across the entire production chain and directly affect plant performance.
As grinding systems age, operating conditions change or product requirements increase, performance losses rarely occur suddenly. Instead, grinding efficiency gradually declines and often remains unnoticed in daily operation. During this process, specific energy consumption increases, wear accelerates and process stability is reduced. Over time, grinding capacity decreases, maintenance shutdowns become more frequent and flexibility for different cement types and additives is limited. Without modernization, these effects continue to grow, leading to higher energy demand, reduced reliability and decreasing overall plant stability.

power savings
Advanced wear protection concepts combined with optimized grinding conditions help reduce mechanical stress on components. This leads to significantly extended service intervals and a much longer component lifetime. By stabilizing operating conditions and minimizing excessive wear, maintenance effort is reduced and equipment remains reliable over a longer operating period.
Power savings are realized through improvements in separation efficiency and a reduction of pressure losses within the grinding circuit. Additional improvements to the grinding method support interparticle comminution, allowing the system to operate more efficiently. Together, these measures significantly reduce energy consumption while maintaining stable grinding performance.
Separator efficiency plays a key role in cement grinding and has a direct impact on overall system performance. Efficient separation supports stable operation and improves the effectiveness of the entire grinding circuit. Modernization of sepol® high-efficiency separators provides a fast and cost-effective way to enhance performance without extensive changes to the existing grinding system.
Depending on the project scope, sepol® separator upgrades or replacements can be completed within very short shutdown periods. This makes separator modernization one of the most effective optimization measures in cement grinding, delivering measurable performance improvements with minimal disruption to plant operation.
KEY BENEFITS
sepol® features a modular and compact design that allows for easy integration into existing buildings, even where space is limited. It offers high separation efficiency and the ability to cool and dry simultaneously. Modernization projects with the sepol® can often be completed within a short downtime of only 5 to 12 days.
When grinding cement, compound cast rollers achieve service lifes of >100.000 hours of operation. This drastically reduces maintenance costs and increase plant availability compared to traditional surface-welding solutions
Combi-grinding combines the High Pressure Grinding Roll with a ball mill. The polycom® handles the highly energy-efficient pre-grinding, while the ball mill ensures the final product characteristics. Shifting more of the grinding work to the HPGR maximizes the overall system efficiency and lowers the specific energy consumption of the entire plant.
In a rapidly evolving industrial landscape, staying competitive means getting more out of the assets you already have. During our upcoming 30–45 minute virtual session, we will show how targeted modernizations can unlock hidden performance potential across your plant, boosting throughput, improving efficiency, and reducing OPEX.
Join our experts from thyssenkrupp Polysius as they provide a compact, high‑value overview of modernization levers across the entire process chain: crushing, raw grinding, clinker grinding, pyroprocessing, and laboratory automation.
