HVM vertical roller mill is an advanced grinding system designed for processing coal, cement raw materials, slag, and various industrial minerals. This high-efficiency equipment integrates drying, grinding, powder selection, and transportation functions in a single compact unit.

• Coal Moisture: <15%
• Coal Power Fineness: R0.08=2-12%
• Coal Power Moisture: ≤1%

• High Pulverized Coal Quality: Advanced dynamic and static separator achieves fineness of 0.08mm with less than 8% screen residue
• High Efficiency & Capacity: 20-50% higher output compared to older vertical mills with reduced power consumption
• Enhanced System Security: Integrated explosion-proof measures including temperature detection and online gas analysis
• Environmental Compliance: Negative pressure system design prevents dust overflow with emissions meeting national standards

HVM vertical mill handles materials with moisture content ranging from 20-30% (calcium carbide slag, lignite) to less than 1% (cement clinker), demonstrating exceptional adaptability to varying material conditions.

The motor drives the grinding plate rotation via reducer. Material enters through the feed port and moves toward the grinding plate edge by centrifugal force. Crushing occurs as material passes through circular grooves, with high-speed airflow carrying crushed particles. Large particles return for regrinding while qualified fine powder is collected through the powder selection system.
