High-Efficiency Limestone Grinding Mills for Glass Production

High-Efficiency Limestone Grinding Mills for Glass Production

Introduction

The glass manufacturing industry demands high-purity limestone powder with precise particle size distribution. Our advanced grinding mills provide optimal solutions for producing ultra-fine limestone powder with superior efficiency and environmental compliance.

Typical Limestone Powder Specifications for Glass Production
Parameter Float Glass Container Glass Specialty Glass
CaCO3 Content ≥98.5% ≥97% ≥99%
D50 Particle Size 8-12μm 15-25μm 3-5μm
Moisture Content ≤0.5% ≤0.8% ≤0.3%
Technology Comparison
Traditional vs. Advanced Grinding Systems

Conventional ball mills suffer from high energy consumption (45-50kWh/t) and wide particle distribution. Our innovative grinding solutions address these challenges through:

  • Precision Classification: Turbine classifiers with 99% separation efficiency
  • Material Science: Hardened alloy grinding components with 8,000+ hour lifespan
  • System Integration: Combined drying-grinding-classification processes
