High-Efficiency Grinding Mill for Coal Water Slurry Preparation
Introduction to Coal Water Slurry Grinding Technology
Coal Water Slurry (CWS) has emerged as a clean coal technology that combines fine coal particles with water to create a pumpable fuel. The preparation process demands specialized grinding equipment capable of achieving ultra-fine particle sizes while maintaining energy efficiency. As a leading manufacturer with over 30 years’ experience in mineral processing, ZENITH has developed advanced grinding solutions specifically optimized for CWS production.
Key Requirements for CWS Grinding
- Particle size distribution: 80% below 75μm
- Solid concentration: 60-70% by weight
- Low viscosity for pumpability
- Stable suspension properties
ZENITH’s Technological Solutions
Our R&D team has developed specialized grinding systems incorporating several patented technologies to meet the exacting demands of CWS preparation:
1. XZM Ultrafine Mill Series
Specifically designed for ultra-fine grinding applications, the XZM Ultrafine Mill achieves remarkable fineness up to 2500 mesh (5μm) with energy consumption 30% lower than conventional mills. Its unique features include:
- Vertical turbine classifier for precise particle size control
- Special wear-resistant materials for coal processing
- Closed-circuit system preventing over-grinding
