1. High material humidity: When the material humidity is high, it is easy to adhere to the inside of the organic fertilizer equipment during the drying process, resulting in clogging of the dryer.

2. The material contains large particles or impurities: if the material contains large particles or impurities, it is easy to block the pipeline and equipment inside the drying process of the organic fertilizer production line.

3. Uneven wind speed in the dryer drum: Uneven wind speed in the dryer drum may lead to material accumulation in some areas, resulting in blockage.

4. The corner design of the roller of the organic fertilizer dryer is unreasonable: the unreasonable corner design may lead to the accumulation of materials at the corner, thus blocking the equipment.

5. Discharge equipment failure: Discharge equipment failure may cause the material can not be discharged in time, and then cause the dryer blockage.

6. Too long drying time: too long drying time will make the material adhere more tightly in the dryer, increasing the risk of blockage.

7. Improper operation: the operator does not operate according to the regulations, which may lead to the blockage of the dryer.

To avoid clogging of the dryer, the following measures can be taken:

1. Strictly control the humidity of the material to ensure that it is not easy to adhere in the drying process.

2. Check the particles and impurities in the material regularly, and clean up in time.

3. Optimize the distribution of wind speed in the dryer drum to make it even.

4. Design a reasonable dryer drum Angle to avoid material accumulation.

5. Check and maintain the discharge equipment regularly to ensure its normal operation.

6. Reasonable control of drying time to avoid too long.

Strengthen the training of operators to familiarize them with the procedures and operating methods.
