How to Choose the Best Calcium Carbonate Grinding Mill for Your Processing Needs
Calcium carbonate is one of the most widely used industrial minerals, with applications ranging from paper and plastics to construction materials and pharmaceuticals. Selecting the right grinding mill for calcium carbonate processing is crucial to achieving optimal product quality, energy efficiency, and production capacity. This guide will walk you through the key considerations and introduce ZENITH’s advanced solutions.
Key Factors in Mill Selection
1. Required Fineness
Calcium carbonate applications demand different particle sizes:
- Coarse grades (45-150μm) for putty and rubber
- Medium grades (10-45μm) for paper and plastics
- Ultrafine grades (<10μm) for high-end coatings and pharmaceuticals
2. Production Capacity
Match the mill’s throughput with your operational requirements:
- Small-scale: 0.5-5 ton/h
- Medium-scale: 5-50 ton/h
- Large-scale: 50-250 ton/h
3. Energy Efficiency
Grinding can account for 60-70% of total energy consumption. Look for mills with:
- Advanced classification systems
- Optimized grinding mechanics
- Intelligent control systems
