How to Control D97 Particle Size of Gangue Powder with Milling Equipment
Controlling the D97 particle size distribution in gangue powder production is a critical challenge for many industrial operations. The D97 value, representing the particle size below which 97% of the material’s mass is found, is a key indicator of product quality and performance in applications ranging from construction materials to industrial fillers. Achieving precise control over this parameter requires not only operational expertise but also the right milling equipment designed for fine and ultra-fine grinding applications.
The Challenge of Gangue Milling
Gangue, the commercially valueless material that surrounds ore minerals, presents unique milling challenges due to its variable composition and hardness characteristics. Traditional grinding equipment often struggles to achieve the narrow particle size distributions required for high-value applications, leading to inefficient production and inconsistent product quality.
Key Factors Affecting D97 Control
Several factors influence the ability to control D97 particle size in gangue powder production:
- Grinding mechanism and principle
- Classifier efficiency and precision
- Feed rate consistency and control
- Material moisture content
- Equipment wear and maintenance status
- System airflow and pressure balance
