As the fertilizer industry upgrades toward granulation and high efficiency, the drum granulator, with its superior granulation capacity, has become a core piece of equipment for fertilizer production lines with an hourly output of 1-5 tons. It provides fertilizer companies with a stable and reliable solution for producing granular fertilizers, suitable for a variety of fertilizer types, including organic fertilizers, compound fertilizers, and bio-organic fertilizers.

The drum granulator’s core advantages lie in its high granulation efficiency, adaptability, and durability. It utilizes a horizontal drum structure with a special guide plate design that allows the material to be thoroughly tumbled and mixed. During the tumbling process, the material is bonded together by its own viscosity or a small amount of adhesive, resulting in a granulation rate exceeding 90%. By adjusting the drum speed (10-20 rpm) and tilt angle (3°-5°), it can produce uniform granules with a diameter of 2-6 mm, meeting the fertilization needs of various applications, such as field crops and commercial fruits and vegetables. When used in a fertilizer production line with an output of 1-5 tons per hour, the drum granulator seamlessly integrates with the mixer at the front end and the dryer, cooler, and screener at the back end. The evenly mixed fertilizer raw materials enter the granulator and are formed into granules. The dryer removes moisture, the cooler cools the material, and the screener selects qualified granules. The entire process is highly automated, requiring only 2-3 operators, significantly improving production efficiency.

The equipment is constructed of high-quality, wear-resistant steel, and the drum interior undergoes a special anti-corrosion treatment to withstand the corrosive components in the fertilizer raw materials, extending its service life by over 30% compared to conventional equipment. Furthermore, the equipment is compact, with a 1-ton-per-hour production line occupying only approximately 50 square meters, making it suitable for rapid commissioning for small and medium-sized fertilizer companies.

Currently, production lines consisting of this drum granulator have been exported to multiple countries. After being introduced to an organic fertilizer plant in South America, the production of granular fertilizers increased by 40%, while reducing fertilizer losses during transportation and application. Customers in Southeast Asia are using this equipment to produce compound fertilizers, and the highly uniform granules are highly favored by local farmers.​
