10 T/H Auto Batching NPK Rotary Drum Fertilizer Plant Line

Achieving consistent NPK nutrient ratios and high hourly output in large-scale commercial fertilizer manufacturing depends on precise formula control and continuous granulation. The 10 T/H Auto Batching NPK Rotary Drum Fertilizer Plant Line is a fully automated turnkey engineering solution engineered specifically for high-capacity production facilities processing complex nitrogen, phosphorus, and potassium chemical blends (such as urea, ammonium sulfate, DAP, MAP, and potassium chloride).

The defining highlight of this production line is its integrated computerized multi-hopper automatic batching system. Utilizing continuous loss-in-weight load cells and variable-frequency belt feeders, the system accurately weighs each raw material component in real time according to precise agricultural formulas, eliminating manual dosing errors. The homogenized powder feeds directly into a heavy-duty 10 T/H rotary drum granulator where steam-assisted or liquid-injected wet agglomeration converts fine materials into dense, perfectly spherical granules. The line seamlessly links automated batching, continuous drum granulation, high-efficiency rotary drying and cooling, multi-deck size screening, anti-caking oil coating, and automated quantitative packaging into a single PLC-controlled system. Built by Gofine Machine as a dedicated factory supplier, this plant line features anti-corrosive rubber/stainless steel drum linings, heavy cast steel drive gears, and closed-loop material recycling, delivering granulating efficiencies over 90% with minimal operational labor.

To ensure operational stability and long-term reliability, the Gofine rotary drum granulator incorporates several precision-engineered features:

• Corrosion-Resistant Interior: The internal drum is lined with specialized UHMW-PE (Ultra-High Molecular Weight Polyethylene) or acid-resistant stainless steel plates. This minimizes material sticking and protects the shell from the corrosive nature of ammoniated compounds.
• Enhanced Granulation Rate: Through the optimization of drum inclination (typically 2.0% to 5.0%) and rotational speed, the system achieves a granulation rate exceeding 90%, with fewer fines requiring recycling.
• Steam Injection Technology: Integrated steam piping allows for the adjustment of material temperature and moisture levels, ensuring optimal plasticity for granule formation without relying on excessive liquid binders.
• Heavy-Duty Transmission: Featuring a large cast steel gear and a high-performance motor-reducer assembly, the unit maintains stable torque even under full-load conditions (capacities ranging from 1 t/h to 20 t/h).

This granulation system is highly versatile and suitable for:

• High-Concentration Compound Fertilizer: Producing formulas like 15-15-15 or 20-20-10.
• Ammoniation Granulation Processes: Integrating liquid ammonia, phosphoric acid, or sulfuric acid.
• Organic-Inorganic Mixtures: Processing bio-organic materials that require a specific moisture-heat balance for pelletizing.

The production sequence in the drum is a coordinated mechanical and chemical process:

• Material Feeding: Base powders (such as Urea, MAP, or Potassium Chloride) are fed into the rotating drum at a constant rate.
• Ammonia/Steam Injection: Under the rolling bed of material, gaseous ammonia steam are injected. The resulting chemical heat and moisture soften the particles.
• Rolling & Agglomeration: As the drum rotates, the softened materials collide and adhere to each other, forming spherical "seeds" that grow into full-sized granules through centrifugal force.
• Discharge: The finished granules exit the drum and are conveyed to drying and cooling units to finalize their structural hardness.
