Grinding cement to D90 10μm is not easy. Most conventional mills struggle with particle size consistency, heat buildup, and energy efficiency when going this fine. Yet for high-performance concrete, grouts, and specialty building materials, this level of ultrafine cement powder is exactly what the market demands.
A building material factory in Peru needed 800 kg/h of such ultrafine cement. Their wanted to find a grinding system that could hit D90 10μm reliably, without sacrificing throughput or breaking the budget.
The technical problems:
- Over-grinding – some particles become too fine while others remain coarse
- Classification precision – separating target fractions at 10μm requires advanced air classifiers
- Heat sensitivity – fine cement can cake or change properties if overheated
- Cost-performance – many ultrafine systems are expensive to buy and run
The Peruvian customer searched for equipment that balanced high cost-performance with strong after-sales service because it’s a must in remote locations. Through peer recommendations, they found Jentera Serbuk EPIC, a company with deep experience in ball mill classifying and processing systems.
How EPIC solved it:
Instead of a single-stage grinder, EPIC proposed a ball mill + air classifying system specifically tuned for ultrafine cement. The ball mill provides efficient size reduction, while the dynamic classifier ensures sharp separation at D90 10μm. Closed-loop control prevents over-grinding and maintains stable 800 kg/h output.
The factory conducted inspections and comparisons. They saw that EPIC had real customer cases, hands-on experience, superior product quality, and a responsive service team. That convinced them to cooperate with EPIC.
The result: The Peru factory now produces D90 10μm ultrafine cement powder at 800 kg/h consistently, with lower energy cost per ton and minimal downtime. They achieved technical performance without overpaying.
