Vertical roller mills (VRMs) have become the preferred solution for slag grinding due to their superior energy efficiency and processing capacity. Unlike traditional ball mills, VRMs utilize a bed compression principle that reduces specific energy consumption by 30-50% while achieving higher throughput rates.
| Parameter | Vertical Roller Mill | Ball Mill |
|---|---|---|
| Specific Power Consumption | 35-45 kWh/t | 50-70 kWh/t |
| Moisture Tolerance | Up to 15% | Max 5% |
| Noise Level | ≤80dB | ≥95dB |
Our technical team recommends the following approaches to maximize slag grinding efficiency:
Maintaining optimal material bed thickness (typically 20-50mm) ensures proper grinding pressure distribution. The LM-Y Vertical Pre-grinding Roller Mill features advanced hydraulic systems that automatically adjust grinding pressure based on real-time material feed rates.
The MRN Pendulum Mill’s innovative square-shaped air ducts reduce turbulence by 18% compared to conventional circular designs, significantly improving classification efficiency while lowering energy consumption.
For slag processing applications requiring both high capacity and ultra-fine output, we propose two optimized solutions:
| Model | Capacity (t/h) | Power (kW) | Moisture Tolerance |
|---|---|---|---|
| LM150Y | 6-10 | 280 | ≤15% |
| LM340Y | 80-100 | 2500 | ≤15% |
| Model | Grinding Rollers | Output (t/h) | Fineness (mesh) |
|---|---|---|---|
| MB5X98 | 3-4 | 2.7-6.5 | 30-325 |
| MB5X298 | 4-6 | 48-83 | 30-325 |
A recent installation using our LM340Y mill achieved:
Both recommended models feature:
For operations requiring ultra-fine slag powder (D97≤5μm), our SCM Ultrafine Mill series provides additional capacity options from 0.5-25 ton/h with energy-saving vertical turbine classifiers.
