1. Causes of abnormal noise
The abnormal noise of the feed extruder equipment may be caused by the following reasons:
1. The equipment has been used for too long, resulting in serious wear of the equipment;
2. The equipment parts are loose or damaged;
3. The equipment is not lubricated enough or the lubricating oil is of poor quality;
4. The poor use environment of the equipment causes dust accumulation or foreign matter to enter the equipment.

2. Treatment method
1. Check the equipment: First, you need to conduct a comprehensive inspection of the feed extruder equipment to determine the location and cause of the abnormal noise. The inspection content includes the equipment's bearings, gears, chains, belts and other components, as well as the equipment's use environment.
2. Replace parts: If the equipment parts are damaged, they need to be replaced in time. It is recommended to use original accessories or accessories that meet the standards to avoid affecting the normal use of the equipment.
3. Lubricate the equipment: Regularly add lubricating oil to the equipment to ensure that the lubrication of the equipment meets the standard requirements. The lubricating oil should be selected for the equipment and replaced regularly.
4. Cleaning equipment: Cleaning equipment can effectively remove dust and foreign matter inside the equipment, reducing friction and wear of the equipment. It is recommended to clean the equipment regularly, especially for equipment in poor use environment.
5. Maintaining equipment: Maintain the equipment regularly, check whether the various indicators of the equipment are normal, ensure the stability of the equipment's performance, and extend the service life of the equipment.
