In the fertilizer production line, the role of the fertilizer mixer is to evenly mix a variety of raw materials to provide suitable materials for the subsequent fertilizer granulator. If the mixer fails in the process of continuous operation for a long time, it will not only affect the production efficiency, but also may lead to a decline in product quality. The following are some common faults and their solutions.

1. Uneven mixing

Failure cause: uneven water content of the material, insufficient mixing time or blade wear.

Solution: Adjust the moisture of raw materials to keep the appropriate humidity; Increase the mixing time to ensure that the material is fully mixed; Check the stirring blade regularly, and replace it in time if it is worn.

2. Bearing overheating or damage

Failure cause: Prolonged operation leads to increased friction, lack of lubrication or bearing damage.

Solution: Fill the bearing with lubricating oil regularly to reduce friction and heat, and check whether the bearing has abnormal wear, and replace the new bearing if necessary.

3. The device vibrates or makes abnormal noise

Failure cause: loose bolt, mixing blade deformation or motor abnormality.

Solution: Check and tighten all bolts regularly to prevent loosening; If the mixing blade is deformed or damaged, repair or replace it in time; Check whether the motor is running normally to avoid abnormal vibration and noise caused by motor failure.

4. Material accumulation or blockage

Failure cause: The residual materials have not been cleaned for a long time, resulting in accumulation and blockage.

Solution: After the completion of each batch of production, clean the inside of the mixer in time to prevent the residual material from drying and affecting the next mixing.

5. Motor overload or burn

Failure cause: too much feeding, unstable voltage or long-term overload operation.

Solution: Control the feeding amount within the range of the equipment, ensure the stability of the power supply, avoid long-term continuous high load operation, and arrange the shutdown cooling time appropriately.

Conclusion

In order to ensure the stable operation of the fertilizer mixer in the organic fertilizer production line, enterprises need to strengthen daily maintenance, reasonable control of the conditions of use, and timely treatment of potential problems, so as to improve production efficiency, ensure the normal operation of the fertilizer granulator and the granulator, and ensure the quality of the final product.
