| The Coal mill hydraulic reversing valve seal MG50.11.22 is a critical element within the hydraulic circuit. Its primary role is to guarantee the sealing integrity of the hydraulic reversing valve, thereby preventing any leakage of hydraulic fluid. The reversing valve, which governs the direction of oil flow, is typically mounted vertically on the coal mill equipment. Under normal and operational states, the electromagnetic reversing valve is positioned to the left, with the hydraulic reversing valve's control oil chamber connected to the oil reservoir. In this configuration, the valve spool is at its uppermost position, allowing the return oil chambers of the three loading cylinders to drain directly back to the oil tank. The sealing assembly's design and choice of materials must be robust enough to endure fluctuations in hydraulic oil pressure and temperature, ensuring consistent sealing effectiveness across a range of operating conditions. This is essential for the smooth functioning of the hydraulic system and the reliable operation of the coal mill. |
| 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. |
