The Sealing ring ring 20MG23.11.09J.15 is installed in the annular groove of the sealing shell of the coal mill base. Its main function is to isolate the hot air inside the coal mill from the outside atmosphere and prevent the hot air from leaking out. Since there is no lubricant between the transmission shaft and the sealing ring during operation, the self-lubricating property of the carbon ring must be very good. The Sealing ring ring 20MG23.11.09J.15 helps prevent the hot air in the coal mill from flowing back into the coal feeder. The sealing fan generates high-pressure air and sends it to the bearings of the rotating parts of the coal mill and the coal feeder to prevent the escape of coal powder airflow. |
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. Maintainability: replaceable stationary wear rings and well-designed lubrication system. |
Application: Thermal power plants: Coal mills are used to grind coal into powder for better combustion and power generation. Steel plant: Coal mills are used for the preparation of coal powder, helping to improve combustion efficiency. Cement plant: Coal mills are used for the preparation of coal powder to ensure the smooth progress of cement production. In the field of coal chemical industry, medium speed coal mills can be used in coal to oil, coal to fertilizer, coal to natural gas and other process flows to provide qualified coal powder. |
