| Fasten bolts 20MG23.11.09J.51 are used to connect various parts of the coal mill, such as the driven flange of the grinding disc support and the reducer, to ensure that the grinding disc support can withstand the grinding force and other pressures when the coal mill is working. Fasten bolts must be able to withstand various mechanical loads generated during the operation of the coal mill, including pressure, torque and vibration. In order to ensure the strength and wear resistance of Fasten bolts, materials with good comprehensive mechanical properties are usually selected, and surface quenching treatment is performed to improve surface hardness and core toughness. In order to prevent bolts from loosening, special anti-loosening designs are often used for Fasten bolts of coal mills, such as locking nuts with spring leaves, disc washers and high-quality temperature-resistant rubber sealing rings. These measures can effectively prevent bolt loosening and leakage of materials, ash, slurry leakage, water seepage and other problems. |
