There may be various problems encountered during the granulation process of organic fertilizers, which may affect granulation efficiency, particle quality, and the operational stability of the entire production line. The following are several common problems and their solutions in the granulation process of organic fertilizers:

1. Insufficient particle strength

Reason: The moisture content of the raw materials is too high or too low, the fiber content in the raw materials is insufficient, and the pressure setting of the organic fertilizer granulator is improper.

Solution strategy: Adjust the moisture content of the raw materials to a suitable range (usually 25% -35%), increase the binder or fiber content appropriately, and optimize the pressure and speed settings of the granulator.

2. Irregular particle shape

Reason: Uneven particle size of raw materials and improper setting of granulator parameters.

Solution: Use a crusher to ensure consistent particle size of the raw materials, adjust the speed of the organic fertilizer granulator and the gap between the pressure rollers to obtain a uniform particle shape.

3. Excessive dust

Reason: The raw materials are too dry or crushed, and the sealing of the granulator is poor.

Solution strategy: Control the moisture content of raw materials, avoid excessive crushing, check and improve the sealing of the granulator, and install a dust collection system.

4. Low granulation efficiency

Reason: Improper pre-treatment of raw materials, insufficient maintenance of organic fertilizer granulator, and unreasonable production parameter settings.

Solution strategy: Optimize the raw material pretreatment process, regularly maintain and clean the granulator, adjust production parameters to improve efficiency.

5. Different particle sizes

Reason: The parameters of the granulator are unstable, and the raw materials are mixed unevenly.

Solution: Use a vibrating screen to screen the particles, ensuring uniform mixing of raw materials and stable working parameters of the granulator.

6. Surface cracks or breakage of particles

Reason: Low moisture content in raw materials, excessive granulation pressure, and improper cooling process.

Solution strategy: Increase the moisture content of the raw materials appropriately, adjust the granulation pressure, ensure uniform cooling of the particles, and avoid sudden temperature changes.

7. Production line malfunction

Reason: Equipment aging, improper operation, and insufficient maintenance.

Solution strategy: Regularly maintain and inspect production line equipment, train operators, and replace worn parts in a timely manner.

8. Cost control

Reason: High energy consumption, waste of raw materials, and low equipment efficiency.

Solution strategy: Adopt energy-saving equipment, optimize production processes, reduce raw material loss, and improve equipment utilization.

Solving these problems requires a comprehensive understanding of the organic fertilizer production line, including raw material characteristics, equipment performance, and operating standards. By continuously optimizing production processes and equipment maintenance, the efficiency and product quality of organic fertilizer granulation can be effectively improved.
