The Coal mill upper static ring 55MG43.11.08.99.01 is a key component inside the coal mill, and its main function is to organize the flow of primary air and coal powder. It cooperates with the dynamic ring to form a sealing structure to ensure that the primary air can effectively deliver the coal powder to the boiler for combustion. The design and performance of the static ring directly affect the air-to-powder ratio, coal grinding output, coal powder fineness and stone coal emission characteristics of the coal mill. The upper part of the static ring is the part that is often worn and is usually designed to be segmented for easy replacement and maintenance. The material and structural design of the static ring need to have good wear resistance and sealing properties to reduce wear and air leakage, thereby improving the operating efficiency of the coal mill and reducing energy consumption. |
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. |
