Moisture Requirements for Organic Fertilizer Disk Granulator Production

During the production of organic fertilizer disk granulator machine, the material moisture content typically needs to be controlled between 30% and 40%. This range is the “golden ratio” for granulation, ensuring that the material has sufficient viscosity to form pellets while preventing excessive moisture from causing particle adhesion or equipment blockage. The “Golden Rule” of Moisture Control Optimal Range: 30% – 40%. This is the state where the material has the highest pellet formation rate and the best particle roundness. Lower Limit Warning: Below 25%. The material is too dry, resulting in excessive powder, difficulty in forming pellets, and loose, fragile particles. Upper Limit Warning: Above 45%. The material is too wet, easily sticking to the walls and clumping, leading to poor discharge or equipment blockage. How to determine if the moisture content is suitable during disc granulator production? The most intuitive method is the “hand-squeezing method”: grab a handful of material and squeeze it tightly. If no water seeps between your fingers, and the material forms a clump when released, but can be easily broken apart with a light touch, then this is the ideal state. What to do if the moisture content is not within the acceptable range? Too dry: Spray an appropriate amount of water or add well-rotted wet material, stirring continuously to ensure even moisture distribution. Too wet: Add dry material (such as straw powder, rice husk powder) or recycled material (dried crushed particles) to absorb excess moisture and adjust to the appropriate state.
