In fertilizer production, the granulation process directly impacts fertilizer application convenience, storage stability, and nutrient utilization. Due to its unique technological advantages, double roller press granulators (commonly known as fertilizer compaction machines) are the preferred equipment for many production scenarios. They can transform a variety of fertilizer raw materials into uniform granules without complex pretreatment, offering both adaptability and practicality.

The operating principle revolves around “physical extrusion.” Crushed and mixed fertilizer raw materials are conveyed between two pairs of counter-rotating extrusion rollers at the core of the equipment. Under pressure from the roller surfaces, the raw materials are compressed into continuous flakes. These flakes then enter a crushing unit, breaking them into irregular particles. Screening equipment then selects the finished product that meets the required particle size.

The core advantages of double roller press granulators lie in their flexibility and energy efficiency. Requiring no binders, granulation relies solely on the raw materials’ inherent physical properties, preserving the natural properties of organic fertilizers or the nutrient purity of compound fertilizers. This eliminates the high-temperature drying step required in traditional granulation. Whether processing organic fertilizer, compound fertilizer, or functional bio-fertilizer, stable granulation can be achieved by simply adjusting parameters such as extrusion pressure and roller speed, providing an efficient solution for fertilizer production.

In the fiery arena of industrial production, materials processed at high temperatures often undergo a crucial step: cooling.

The Art of Cooling: Working Principle of Drum Cooler

Imagine materials fresh from high-temperature treatment, carrying intense heat and urgently needing cooling. The drum cooler acts like a skilled temperature regulator, smoothly transitioning materials from high temperatures to suitable levels through exquisite heat exchange processes. When high-temperature materials enter the rotating drum through the feed inlet, a carefully choreographed cooling dance begins.

Within the sophisticated npk fertilizer production line, the cooling drum’s elevator acts as a deft conductor, continuously lifting and dumping material to form a uniform particle curtain. This crucial process in the complete npk fertilizer line ensures optimal product quality after materials have been precisely blended by the npk blending machine and formed through granulation equipment.

Simultaneously, the cooling medium (whether air, water, or refrigerant) comes into close contact with the material, removing excess heat through efficient heat exchange. This rapid, uniform cooling process is essential for stabilizing output from various granulation systems, whether from a disc granulator in a specialized disc granulation production line or other types of fertilizer granulator equipment.

The same precision cooling technology benefits both conventional and organic fertilizer production line operations, ensuring every particle receives perfect thermal treatment regardless of the production method, ultimately guaranteeing consistent fertilizer quality and performance.
