A well-established mineral processing company in Greece was facing growing pressure from its industrial buyers. The paints and sealants manufacturers they supplied needed a finer and more reliable calcium carbonate powder. Unfortunately, their existing air classifier mill grinding line could not produce a consistent particle size, which led to frequent customer complaints and wasted batches.
How Epic Powder Solved the Grinding Challenge
After evaluating the application, Epic Powder recommended the MJW Air Classifier Mill. This system combines a grinding rotor for size reduction with a high-precision air classifier for sharp separation. The complete setup also included a pulse-jet bag filter to ensure clean operation, which was important for the client’s environmental compliance.
Measured Results That Changed Their Production
Once the new mill was installed, the Greek customer achieved a d97 45μm particle size, meeting the premium standard for sealants and coating applications. Production consistency jumped to 99.5% within the target range, and energy consumption dropped by 15% compared to their old line. The throughput now sits comfortably at 3 to 4 tons per hour for ultrafine calcium carbonate.
What the Customer Says About Epic Powder
According to the production manager, the classifier mill has transformed their operations. The technical support from Epic Powder was responsive throughout installation and commissioning, and the improved powder quality has helped them enter new markets that were previously out of reach.
Why This Matters for Calcium Carbonate Producers
This case shows that upgrading to a modern air classifier mill does more than just improve particle size. It reduces waste, lowers energy costs, and opens doors to higher-value customers. For any calcium carbonate producer in Europe looking to move beyond commodity powders, the return on investment can be faster than expected.
