During the operation of the fertilizer production line, the fertilizer granulator may have the problem of blocking material, resulting in equipment shutdown and affecting production efficiency. Especially in the NPK fertilizer production line, factors such as raw material humidity, feed amount and equipment parameters will affect the stable operation of the granulator. Faced with the problem of material blocking, enterprises should adopt standardized operations to ensure smooth production. Here are three effective solutions.

1. Stop the machine immediately and check the cause of material blockage

When the pelletizer is found to be blocked, the operation of the equipment should first be stopped to prevent the motor from being burned by overload. At the same time, check the material condition to determine whether the material is blocked due to high humidity, too fine particles or too much impurities. If it is a humidity problem, you can adjust the drying process appropriately; If it is an impurity problem, it is necessary to optimize the screening system to avoid unqualified materials entering the granulation process.

2. Use proper cleaning methods to avoid device damage

When cleaning the blocked material, it is strictly forbidden to use hard objects or tools to hit the inside of the granulator directly, so as not to damage the granulation disc or extrusion roll. If the blockage is light, you can manually rotate the spindle to slowly remove the material; For serious blockage, you can remove part of the components for cleaning, and check whether there is residual hard debris affecting the operation.

3. Adjust the process parameters to prevent plugging again

After cleaning up the blocked material, the operation parameters of the granulator should be properly adjusted. For example, control reasonable feed speed to avoid putting too much material at one time; Adjust the pressure of the pelletizer or the roller extrusion pelletizer to make the material forming more uniform. At the same time, regularly check the transmission system, lubrication parts and screening devices to ensure long-term stable operation of the equipment.

Conclusion

In the face of pelletization machine blockage, enterprises should adopt standardized operation processes, stop the machine in time for inspection, correct cleaning of the blockage, and optimize production parameters to reduce the incidence of failure. Through these measures, it can effectively improve the stability of the fertilizer production line, ensure the efficient operation of the NPK fertilizer production line, and improve the production efficiency of the enterprise.
