    Project Scope: Fertilizer production line equipment, process design and plant engineering services. Finished fertilizer products are not supplied.

    Choose the Right NPK Granulation Process

    Different NPK formulations require different granulation processes. SYM designs fertilizer granulation plants around your raw material properties, target capacity, finished granule size, available utilities and investment plan.

    Compare the three main solutions below to select the right granulation process for your NPK fertilizer production line.

    Rotary Drum Wet Granulation
    Best for medium- to large-scale NPK fertilizer manufacturing plants requiring continuous output and flexible formulations. The wet granulation process combines stable rotary drum operation with drying, cooling and closed-loop screening for reliable high-capacity production.
    Double Roller Dry Granulation
    Best for powder formulations that can be compacted without adding water or steam. By eliminating conventional drying and cooling, this dry granulation line offers lower energy demand, a compact layout and a shorter process for small- to medium-capacity NPK plants.
    Disc Granulation
    Best for NPK projects requiring flexible operation and convenient adjustment of granule formation. For suitable formulations, the disc angle, rotation speed, feeding rate and liquid addition can be adjusted to help control the granulation process and finished particle size.

    Core Production Process

    Our compound fertilizer production line follows a streamlined, efficient workflow:

    1. Precision Batching

    The required raw materials are accurately proportioned according to the target NPK formula, helping maintain consistent nutrient ratios and stable production.

    2. Homogeneous Mixing

    A dual-shaft paddle mixer achieves thorough 3D blending (CV ≤ 5%), creating ideal conditions for uniform granulation.

    3. Efficient Granulation

    A large rotary drum granulator forms high-strength particles via liquid-phase binding or additives. Alternative processes like double roller dry granulation or disc granulation are available based on material properties.

    4. Intelligent Drying

    The rotary dryer, with adjustable concurrent/counter-current airflow and optimized lifting flights, stabilizes moisture content at ≤2.0%, enhancing particle physical strength.

    5. Uniform Cooling

    A rotary cooler brings hot granules to near ambient temperature, preventing caking and fixing particle structure.

    6. Precise Screening

    Multi-layer vibrating screens separate finished granules (2–4 mm / 3–5 mm). Oversize and undersize materials are automatically crushed and recycled, achieving a raw material utilization rate >98%.

    7. Finished Product Coating

    Equipped with a rotary coating machine, the finished fertilizer undergoes functional treatments such as anti-caking, moisture resistance, or controlled-release coating, effectively enhancing product added value and market competitiveness.

    8. Automatic Packaging & Palletizing

    High-speed bagging scales (±0.2% accuracy) and optional robotic palletizers handle the final steps from production to warehouse.
