Clinker pulverisers are critical equipment in cement and aggregate processing lines, designed to reduce hardened clinker nodules into fine powder for further blending or direct use. Modern vertical roller mills (VRM) and ball mills dominate this sector due to their high efficiency and adjustable particle size control.
| Model | Capacity (t/h) | Power (kW) | Output Size (μm) |
|---|---|---|---|
| VRM-2800 | 50-70 | 1600 | 30-80 |
| Ball Mill Φ3.2x13m | 45-60 | 1600 | 45-100 |
| HPGR 1400/800 | 120-150 | 2×500 | Cracked microstructure |
The optimal clinker grinding line typically includes:
1. Pre-crusher (jaw/impact type for <100mm feed)
2. Bucket elevator with dust-proof design
3. Proportional feeding system (±1% accuracy)
4. Pulse jet bag filter (emission <20mg/Nm³)
Q: How to prevent excessive temperature rise?
A: Install water spray systems maintaining mill exit temp <110°C.
Q: Wear-resistant solutions?
A: Hardfaced rollers (HRC58+) or ceramic-lined grinding chambers.
Q: Energy saving measures?
A: Waste heat recovery can reduce power consumption by 8-12%.
