The lower seal core 20MG40.12.06-D-1 of the coal mill is a key sealing component in the coal mill, mainly used to prevent the leakage of coal powder and air, to ensure the normal operation of the coal mill and the sealing of the system. Role and function: 1. Prevent leakage: The lower seal core 20MG40.12.06-D-1 is installed at the bottom of the coal mill. Its main function is to prevent the coal powder and air generated during the coal grinding process from leaking from the bottom of the coal mill to the external environment. This sealing effect is essential for maintaining the pressure balance inside the coal mill and preventing environmental pollution. 2. Protect equipment: Through effective sealing, the lower seal core 20MG40.12.06-D-1 can reduce the wear of coal powder on the internal components of the coal mill and extend the service life of the equipment. At the same time, it can also prevent external impurities from entering the coal mill and avoid interference with the coal grinding process. 3. Improve efficiency: Good sealing performance helps to improve the working efficiency of the coal mill. It can ensure that the airflow and coal powder flow inside the coal mill are more stable, thereby improving the grinding quality of coal powder and the overall performance of the system. |
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. |
