Best Coal Powder Grinding Mill for Foundry Industry
Introduction to Coal Powder Grinding in Foundry Applications
The foundry industry relies heavily on high-quality coal powder as a carbon additive and energy source in metal casting processes. Efficient grinding systems are critical for achieving optimal particle size distribution (typically 200-325 mesh) to ensure complete combustion and uniform mixing with molding sands. This article explores the technical requirements and presents the most advanced grinding solutions for foundry coal preparation.
Key Requirements for Foundry Coal Grinding
- Precise Particle Control: 80-90% particles between 45-200μm
- Low Iron Contamination: <0.5% Fe₂O₃ content
- Moisture Stability: Consistent 1-2% moisture retention
- High Thermal Efficiency: 5500-6500 kcal/kg calorific value preservation
