| The main function of the roller sealing air ring 20MG23.11.09J.10 is to prevent coal powder from entering the roller, to prevent coal powder from damaging the oil seal and bearing inside the roller, and to ensure the normal operation of the roller. The sealing air flows through the inner cavity of the roller frame to the outside of the oil seal of the roller and the air sealing ring between the roller frames, forming a clean annular seal to prevent the intrusion of coal powder. The structural design of the roller sealing air ring includes an inner air ring and an outer air ring. The inner air ring is installed on the tray of the coal mill, and the outer air ring is sleeved on the circumferential outer side of the inner air ring, and a cavity with blades installed is formed between the inner air ring and the inner air ring. The roller sealing air ring helps prevent coal powder from contaminating the oil system inside the roller and avoids equipment failures caused by contamination. |
| Technical parameters of coal mill Heat generation: 1631MJ/kg Surface moisture:< 18% Grindability system: HGI=4080 Combustible volatile matter: 1640% Raw coal particles: 040mm Fineness of coal powder: R90=240% |
| Product Features: 1. Reliability: Adopting high-quality bearing support and replaceable stationary wear rings. 2. Efficiency: The dual suction design improves suction efficiency. 3. Flexibility: Suitable for various industrial and municipal fields. 4. Stability: Maintain a high degree of sealing during operation, without leakage. 5.
