High Efficiency Energy Conservation Vertical Coal Mill for Cement, Coal, and Ore Grinding
Key Features
✅ High Grinding Efficiency – Specially designed for coal pulverization, achieving 5-75μm fine powder with uniform particle size.
✅ Low Energy Consumption – Compared to ball mills, it consumes 40% -50% less energy, reducing operational costs.
✅ Durable & Reliable – Wear-resistant rollers and grinding plates, lifespan up to 8,000 hours.In addition, the grinding roller sleeve can be flipped over for use, extending the service life of wear-resistant materials;
✅ Environmentally Friendly – Closed-system operation minimizes dust pollution, meeting ISO environmental standards.
✅ Automated Control – PLC system for real-time monitoring and adjustment, ensuring stable output.
Working principle:
The material enters from the feed port of the mill and falls onto the rotating grinding disc. The grinding disc rotates under the drive of the transmission device, generating centrifugal force that moves the material towards the edge of the grinding disc. During the movement, the material is gradually crushed and ground by the rolling and grinding action of the grinding roller. At the same time, the hot air introduced from the bottom of the mill blows up the ground coal powder, forming a gas-solid two-phase flow. In the rising process, the pulverized coal is graded through the separator, and the qualified pulverized coal is discharged from the mill with the airflow and enters the subsequent pulverized coal collection system; Unqualified coarse powder is returned to the grinding disc under the action of gravity for further grinding.
