| Hexagonal screws 20MG40.11.09.64J play an important role in connecting and fixing in coal mills. The structure of coal mills is complex and contains many parts and components. Hexagonal screws are used to firmly connect these parts together to ensure that the equipment will not loosen due to vibration or impact during operation. For example, in the connection between the grinding bowl and the grinding bowl shell, the hexagonal screws are used to fasten the grinding bowl shell to the gear box to ensure the stable operation of the grinding bowl. In addition, hexagonal screws 20MG40.11.09.64J are also used to adjust and maintain certain parts of the coal mill. During the overhaul of the coal mill, the hexagonal screws can be loosened to inspect and replace the parts. For example, when adjusting the gap between the grinding roller and the grinding bowl, it is necessary to loosen the hexagonal nut on the grinding roller limit bolt. This design makes the maintenance and overhaul of the coal mill more convenient and improves the maintainability and reliability of the equipment. |
