2. Material moisture content is too high or too low. If the water content of the material is too high, it will cause the viscosity of the material to be too high, resulting in difficult discharge; If the water content of the material is too low, it will cause the material to be too loose and easy to leak out from the organic fertilizer equipment.

3. The speed of granulator is not stable. The speed of the granulator directly affects the extrusion and cooling of the material, if the speed is unstable, it will cause the extrusion and cooling of the material to be uneven, resulting in unstable discharge.

4. The scraping device in the granulator is worn. The function of the scraping device is to maintain the uniform distribution of the material in the granulator and prevent the material from leaking out of the granulator, if the scraping device is seriously worn, it will cause the uneven distribution of the material and leakage, resulting in unstable discharge.

5. The heating and cooling system in the granulator do not match. If the heating and cooling systems do not match, the material temperature will change too much, resulting in unstable discharge.

The above is the main cause of the disc granulator discharge instability, by improving the particle size distribution of raw materials, controlling the material moisture content, stabilizing the speed of the granulator, replacing the worn scraping device and adjusting the matching degree of heating and cooling system, can effectively solve the problem of disc granulator discharge instability.
