Product Description

The NPK fertilizer granulator is a specialized piece of equipment designed for granulating NPK compound fertilizers. NPK fertilizer granulation is widely used in agricultural production. Once granulated, fertilizers are not only easier to store and transport but also simpler to apply, thereby improving fertilizer utilization rates. This plays a significant role in increasing crop yields and agricultural production efficiency. Whether you operate a small or medium-sized farm or a large-scale fertilizer manufacturing plant, the NPK fertilizer granulator is your best choice.

Tianci Heavy Industry offers three types of NPK fertilizer granulators for your selection: drum granulators, disc granulators, and double roller extrusion granulators. You can choose the equipment that best suits your farm or factory based on its scale, or contact us directly for a free customized solution.

Drum Granulators

Disc Granulators

Double Roller Extrusion Granulators

Drum Granulators for Large-Scale Production Lines

The drum granulator, also known as a rotary drum granulator, aggregates powdered materials into spherical granules through moistening, rolling, and collision. It is commonly used for granulating NPK compound fertilizers, organic fertilizers, and animal feed. This equipment features high output, making it suitable for continuous production in large-scale fertilizer granulation plants. It achieves a high granulation rate, producing uniform, dense granules that are resistant to breakage. It is simple to operate, runs stably, and offers a high degree of automation.

Pellets Produced By a Rotary Drum Granulator

Disc Granulators For Small And Medium-Scale Production Lines

Disc granulators utilize the combined effects of centrifugal force, friction, and gravity to lift, drop, and continuously tumble the material, causing it to agglomerate into spheres. They are commonly used for granulating NPK compound fertilizers, organic fertilizers, and similar products. By adjusting the material moisture content and disc rotation speed, pellet size and strength can be controlled. These machines produce highly uniform pellets, feature a simple structure, and require minimal investment, making them the optimal choice for small and medium-sized granulation plants.

Double Roller Extrusion Granulators For Small And Medium-Scale Production Lines

Double roller extrusion granulators utilize two counter-rotating rolls to force the material into the holes on the roll surfaces, forming dense granules. They are suitable for both organic and compound fertilizers. The resulting granules are flat in shape, with high granulation efficiency, high strength, and low energy consumption. They operate at room temperature and do not require drying. The equipment features low noise, smooth operation, superior quality, and a longer service life.
