Compound Fertilizer Stirring Gear Granulation Production Line Core Definition & Core Purpose

• Key Concept: It uses a “stirring gear granulator” as the core equipment, combining mechanical stirring, gear extrusion, and material collision to granulate powdery compound fertilizer raw materials (e.g., urea, ammonium phosphate, potassium chloride, and trace element additives) into uniform, round granules.
• Core Purpose: Produce high-quality compound fertilizers with controlled nutrient ratios (e.g., 15-15-15 NPK, 12-18-15 NPK), stable granule shape, and good water solubility/granule strength—meeting agricultural needs for efficient, targeted fertilization.

Working Principle of Stirring Gear Granulation (Core Process)

1. Material Preparation: Powdery raw materials are proportioned, crushed, and mixed with water/binder to form a wet mixture with suitable viscosity and moisture.
2. Granulation: The wet mixture is fed into the stirring gear granulator. The rotating paddles push the material forward and agitate it violently, while the gear plates (fixed on the barrel wall) create resistance and shear force. This combined mechanical action (stirring + extrusion + friction) causes the powder to aggregate into dense, round granules (particle size: 2-4mm, adjustable).
3. Post-Treatment: Granules are dried to remove excess moisture, cooled to prevent caking, screened to ensure uniformity, and finally packaged as finished products.

Key Characteristics & Advantages

• High Granulation Efficiency: The stirring-gear combination enables fast granulation (production capacity: 5-50 tons/hour, depending on model), with a granulation rate of 85%-95% (far higher than traditional disc granulation for some materials).
• Uniform Granule Quality: Granules are spherical/oval, with consistent particle size (2-4mm adjustable) and high mechanical strength (not easy to break during transportation).
• Flexible Nutrient Ratio: Adaptable to different compound fertilizer formulas (e.g., high-nitrogen, high-phosphorus, or trace element-rich fertilizers) by adjusting raw material proportions.
• Low Energy Consumption: Compared to extrusion granulation, it requires less pressure and energy; the wet granulation process avoids high-temperature melting, preserving nutrient activity.
• Automated & Continuous Operation: The entire line can be equipped with PLC control systems for automatic batching, mixing, granulation, and screening—reducing labor costs and ensuring stable product quality.

Compound Fertilizer Stirring Gear Granulation Production Line Application Scenarios

• Large/Medium-Scale Fertilizer Plants: Ideal for industrial production of compound fertilizers (NPK fertilizers), organic-inorganic compound fertilizers (mixing organic matter with chemical nutrients), and specialty fertilizers (e.g., slow-release fertilizers, water-soluble compound fertilizers).
• Agricultural Cooperatives & Plantations: Suitable for customized fertilizer production (e.g., tailored nutrient ratios for crops like rice, wheat, vegetables, or fruits) to meet specific regional or crop needs.
• Waste Resource Utilization: Can process agricultural/industrial wastes (e.g., livestock manure, crop straw, sludge) into organic-inorganic compound fertilizers after composting and mixing with chemical nutrients—supporting circular agriculture.
