    The Rotary Drum Cooler​ is an essential downstream piece of equipment for any high-temperature granulation or drying process. It is designed to rapidly reduce the temperature of hot, freshly processed materials (such as fertilizer granules, pellets, or minerals) using ambient air.
    By employing a counter-flow air-swept design, the cooler ensures uniform heat exchange between the material and the cooling air. This process is critical for preventing caking, improving product hardness, and ensuring materials are safe for bagging, storage, and transportation.

    Working Principle

    The cooling process relies on forced convection and controlled residence time.
    1. Feeding:​ Hot material (typically 60°C–120°C) enters the rotating drum via a sealed inlet.
    2. Lifting & Showering:​ As the drum rotates, internal flights (lifters)​ lift the material and shower it through the air stream. This maximizes the surface area exposed to the cooling air.
    3. Counter-Flow Heat Exchange:​ Cold air is drawn into the drum from the discharge end, moving opposite to the material flow. This counter-flow design achieves the highest thermal efficiency.
    4. Discharging:​ The cooled material exits the drum at a safe temperature (Ambient + 5°C to 15°C), while the heated exhaust air is directed to dust collection systems.

    主な特長

    ✔️Optimal Cooling Performance:​ Reduces material temperature to Ambient + 5°C ~ +15°C, preventing moisture condensation during storage.
    ✔️Prevents Caking:​ Rapid cooling stabilizes the crystal structure of granules (especially NPK), ensuring free-flowing product.
    ✔️Robust Construction:​ Heavy-duty steel drum with wear-resistant lifters designed for continuous 24/7 operation.
    ✔️Energy Efficient:​ Utilizes ambient air instead of refrigeration, minimizing operating costs.
    ✔️Dust Control:​ Integrated air seals and optional cyclone dust collectors maintain a clean working environment.
