In the mineral processing industry, energy efficiency has become a critical factor in equipment selection. Vertical roller mills (VRMs) have emerged as the preferred solution due to their superior energy-saving performance compared to traditional ball mills. This article explores the technical mechanisms behind VRM’s energy efficiency and highlights two exemplary products from our portfolio that embody these advantages.
Unlike ball mills that use impact and attrition between grinding media, VRMs employ a more efficient material bed compression method. The concentrated pressure applied by rotating rollers onto a thin material layer reduces energy waste through:
Parameter | Ball Mill | Vertical Roller Mill | Reduction |
---|---|---|---|
Specific Energy (kWh/t) | 35-45 | 15-25 | 40-50% |
Noise Level (dB) | 90-110 | 75-85 | 20-30% |
System Efficiency | 40-50% | 70-80% | +30% |
VRMs combine multiple processing stages into a single compact unit:
Our SCM Ultrafine Mill represents the pinnacle of energy-efficient fine grinding technology:
Model | Capacity (t/h) | Power (kW) | Energy Efficiency Index |
---|---|---|---|
SCM800 | 0.5-4.5 | 75 | 0.83 kWh/kg |
SCM1680 | 5.0-25 | 315 | 0.68 kWh/kg |
For large-scale operations, the LM-Y series delivers unmatched energy savings:
