MP255Medium-speed coal mill
Pitch Diameter of Grinding Wheel:2550mm | Output:79.3t/h
Product Features
- • Low-speed, large-roll diameter, and high-loading-force design for optimal grinding mechanics and the widest range of applicable coal types
- • Even grinding force transmission; rollers swing within 12-15° to adapt to varying material layer thickness
- • Vertical loading design: Load is transmitted directly to the foundation, enabling high load capacity without vibration.
- • Strong grinding capability, high primary air velocity (70-90 m/s), and low reject coal content (≤0.05%)
- • Lift roller enables easy operation with no-load start/stop
