The problem of screw conveyor blockage in organic fertilizer equipment may affect production efficiency and equipment life. Here are some common causes and solutions:

1. The moisture content of the raw materials is too high: control the moisture content of the raw materials, dehydrate them before processing, and ensure that the raw materials are within the appropriate humidity range.

2. The raw material particles are too large or uneven: before the raw materials enter the screw conveyor, use screening equipment to remove larger particles to ensure uniform particle size.

3. Improper design of the screw conveyor: Solution: Adjust the design parameters of the screw conveyor according to the characteristics of the raw materials to ensure that it can effectively handle the materials to be transported.

4. Wear or damage of the spiral blades: Check the wear of the spiral blades regularly and replace or repair them if necessary.

5. The equipment is not installed horizontally: ensure that the screw conveyor is installed horizontally and make appropriate adjustments and corrections.

6. Overload or overload operation: avoid overload use, operate according to the load range of the equipment manual, and add auxiliary equipment to share the load when necessary.

7. Foreign matter enters: add filtering devices during the raw material processing process to ensure that foreign matter is effectively removed.

8. Insufficient maintenance and cleaning: Clean and maintain the screw conveyor regularly to ensure that there is no accumulation inside.

Through these methods, the blockage problem of the screw conveyor can be effectively reduced and solved, ensuring the smooth production of organic fertilizer.
