The sealed air duct 20MG40.11.12.07 of the coal mill is an important component in the coal mill system. It is mainly used to prevent the leakage of coal powder and gas, ensure the normal operation of the coal mill and maintain a good working environment. The sealed air duct introduces clean high-pressure air to form a sealed airflow to prevent coal powder from entering the roller bearings and other key components, thereby avoiding contamination of the lubricating oil system and causing equipment failure. In addition, the sealed air duct 20MG40.11.12.07 also plays a role in protecting the environment by preventing the leakage of coal powder and gas and reducing pollution to the surrounding environment. During the operation of the coal mill, the sealed air duct needs to be regularly maintained and inspected to ensure its good sealing performance and avoid equipment damage and environmental pollution caused by poor sealing. |
