Heavy calcium carbonate (CaCO₃) is one of the most widely used industrial minerals, serving as a filler and functional additive in plastics, coatings, paper, and construction materials. High-performance applications demand ultrafine, high-purity powder, which cannot be achieved efficiently with conventional ball or Raymond mills.
Application Requirements and Challenges
Plastics & Rubber: Improves rigidity, impact resistance, and surface finish.
Paints & Coatings: Enhances opacity, dispersion, and durability.
Paper: Provides brightness, smoothness, and improved print quality.
Producing powders in the 2–10 μm range while maintaining energy efficiency and purity presents a significant technical challenge.
LUM Ultrafine Vertical Mill – Key Advantages
Liming's LUM Ultrafine Vertical Mill integrates grinding, classification, and drying in one compact system, making it highly efficient for heavy calcium carbonate processing.
High Efficiency, Low Energy Use: Consumes 30–50% less energy than ball mills.
Precision Particle Control: Advanced dynamic classifier maintains D97 between 5–45 μm.
Clean, High-Purity Output: Special wear-resistant or ceramic rollers minimize contamination.
Automation & Reliability: PLC system ensures consistent quality with minimal manual intervention.
Proven Industrial Performance
Large Capacity: Up to 50 tons per hour, depending on material properties.
Eco-Friendly Operation: Pulse dust collection and enclosed system minimize emissions.
Cost Efficiency: Lower energy bills and reduced wear-part usage improve long-term ROI.
Conclusion
The LUM Ultrafine Vertical Mill provides an advanced, high-capacity solution for heavy calcium carbonate grinding. By delivering stable ultrafine powders with low energy use and minimal contamination, it enables industries like plastics, coatings, and paper to achieve superior product quality and improved efficiency.
