Continuous Mill – Italy

Country: Italy Scope: Calcium carbonate (CaCO₃) grinding and micronization Material origin: Incoming calcium carbonate (silos/big bags/raw material area) Storage: Feed buffer and incoming batch/quality management Downstream management: Particle size classification/separation, dedusting, product conveying Destination: Micronized product ready for final storage and packaging/shipping Focus: Particle size stability, process continuity, reduction of downtime and consumption, dust control

Objective

To restore and enhance the performance of a continuous mill dedicated to CaCO₃, ensuring more stable particle size distribution, greater operational reliability, and more efficient process management (feeding, grinding, classification, and discharge), while reducing waste and plant downtime.

Implementation

Zetacer managed the revamping design and functional update of the line, addressing critical points in the grinding circuit and material flows to improve feeding regularity and yield repeatability. The project involved optimizing the integration between the continuous mill and the classification/conveying system, using control logic more consistent with production needs to make the plant more stable, manageable, and ready for future upgrades.
