The particle size produced by the organic fertilizer disk granulator can be controlled through adjustments to five aspects: disc angle, rotation speed, feed rate, water spray humidification, and powder particle size, ensuring a stable output of uniformly sized particles.

Adjusting the disc angle is crucial. A larger angle results in faster material descent and smaller particles; a smaller angle increases the material's tumbling time within the disc, allowing particles to grow larger. The standard angle is between 45° and 55°, with minor adjustments as needed to change the particle size range.

Appropriately adjusting the rotation speed of the fertilizer production mahcine is also important. Higher speeds result in greater centrifugal force, slower particle agglomeration, and smaller finished particles; lower speeds increase the material's tumbling time, leading to better adhesion and larger particle diameters. Maintain a stable rotation speed based on the target particle size, avoiding frequent speed changes.

Controlling the feed rate and powder state is also crucial. Insufficient feed at one time hinders continuous particle growth, resulting in smaller particles; sufficient and uniform feed promotes steady particle growth. The raw materials are ground to a uniform fineness. Excessive fine powder easily forms small particles, while moderately coarse powder produces larger particles. Pre-screening ensures the raw material particle size is standardized.

Precise control of water spraying and humidification is crucial. Insufficient moisture results in loose powder that doesn't clump together, leading to smaller, more fragile particles. Appropriate water spraying increases viscosity, making it easier for the material to coalesce into larger particles. Excessive moisture causes clumping and sticking to the granulation tray. Controlling the moisture level and ensuring even spraying guarantees uniform particle growth and formation.

Managing auxiliary materials and granulation time is essential. Adding binder materials as needed helps increase particle size. Shortening the discharge cycle results in smaller particles, while extending the tumbling time in the tray increases particle size. Regularly checking particle size during production and simultaneously fine-tuning the angle, rotation speed, and water volume corrects deviations promptly, ensuring a stable output of standard-sized particles.
