How to prevent maize hammer mill from clogging?

Here are some ways to prevent maize hammer mill from clogging:

1. Control feed quality
Make sure the corn is dry and free of impurities. Wet corn is easy to clump, increasing the risk of clogging, so the corn can be dried before feeding to keep its moisture content within the appropriate range, generally 12% - 14%. At the same time, remove impurities such as stones and metals from the corn through screening equipment to prevent them from entering the crushing chamber, damaging the equipment, or causing clogging.

2. Optimize the feeding method
Use a uniform and stable feeding method to avoid sudden excessive or insufficient feed volume. A quantitative feeding device, such as a screw feeder or a vibrating feeder, can be installed to accurately control the feed speed so that the corn can enter the crushing chamber evenly. In addition, the feed volume should be reasonably adjusted according to the production capacity and crushing effect of the equipment. It is generally recommended that the feed volume be controlled at about 80% - 90% of the rated output of the equipment.

3. Choose a suitable screen
Choose a screen with a suitable aperture according to the required corn powder particle size. If the aperture of the screen is too small, the material will not be discharged smoothly and it is easy to cause blockage; if the aperture is too large, it will affect the product quality. At the same time, ensure that the quality of the screen is good, without damage, deformation, or blockage, and clean and replace the screen regularly. Generally, clean the screen every 8-10 working hours, and check whether the screen needs to be replaced every week.

4. Regular maintenance of equipment
Regularly check the various components of the equipment, especially the hammer, screen discharge port, and other parts that are prone to blockage. Clean the accumulated materials around the crushing chamber and the discharge port in time to prevent the material from agglomerating and accumulating. At the same time, check the wear of the hammer and replace the hammer with severe wear in time to ensure the crushing effect and the normal discharge of the material. In addition, ensure that the ventilation system of the equipment is good to avoid excessive pressure in the crushing chamber due to poor ventilation, which affects the discharge of materials.

5. Monitor equipment operation
During the operation of the equipment, pay close attention to the operating status of the equipment, such as current, voltage, temperature, and other parameters. When the equipment is found to be operating abnormally, such as a sudden increase in current, abnormal sound, or excessive temperature, the machine should be stopped for inspection and troubleshooting in time to avoid the continued operation of the equipment in a faulty state, which may lead to blockage or other more serious problems.
