These photos capture key moments of the shipment process: inside the container, the massive rotary drum granulation main body stands prominently, while the large gear, support roller bases, and geared motors are arranged in an orderly fashion. Precision equipment, such as electrical control cabinets, is protected by reinforced packaging and secured with crisscrossed steel cables, firmly locking all components in place to ensure safety during the long sea voyage. This rotary drum granulation production line is a custom project for a Ukrainian client. After comparing various options, the client selected Huaqiang Heavy Industry’s complete fertilizer equipment suite to build an automated fertilizer processing plant. They plan to utilize abundant local agricultural waste to produce granular organic and compound fertilizers for nearby farmers, thereby seizing opportunities in the local green agriculture sector. The rotary drum granulation process is widely used in the fertilizer industry; ...

A project to install a 100,000-ton annual capacity organic fertilizer production line at a large cattle farm in Dazhou, Sichuan, has recently entered the intensive equipment installation phase. Huaqiang Heavy Industry is supplying the complete set of organic fertilizer production equipment and providing installation guidance. Upon completion, the facility will enable the large-scale, harmless treatment and resource utilization of livestock waste, such as cattle manure. The installation site within the steel-structure workshop is a hive of activity. A large rotary drum granulator is being slowly lifted by a crane and precisely positioned under the direction of on-site technicians. As the core component of the production line, the granulator features a drum made of thickened steel plate and operates smoothly via an external gear ring drive; it transforms fermented, decomposed cattle manure into uniform spherical granules. On the other side of the workshop, auxiliary equipment—includin...

Large rotary drum equipment sits securely on the flatbed truck; as the loading process concludes, the rotary drum granulation fertilizer production line —custom-built by Huaqiang Heavy Industry for a Nigerian client—officially sets off for the African continent, marking the start of a new overseas project journey. With many African nations vigorously promoting local fertilizer manufacturing to reduce reliance on imports, the market for fertilizer production equipment in Nigeria is experiencing rapid growth. The delivered rotary drum granulation line is capable of producing both organic and compound fertilizers. It processes various organic raw materials—such as crop stalks and livestock manure—using a wet drum granulation process to yield uniform, spherical, and durable fertilizer granules. These granules are easy to store, transport, and apply in the field, making them ideally suited to the needs of local farmers. To meet the specific requirements of this overseas project, Huaqiang He...

The biggest highlight of rotary drum granulator is its strong adaptability to raw materials. It covers almost all powdery and finely divided fertilizer raw materials. It does not require complicated modification processing and is suitable for the production of organic fertilizers, compound fertilizers, biological fertilizers and other categories. It can be divided into three major categories: 1. Organic raw materials Decomposed livestock and poultry manure (chicken manure, sheep manure, cow manure, pig manure), crushed straw, sawdust, fungus residue, sugar residue, sludge, kitchen fermentation materials, cakes and other agricultural and industrial organic waste are the core processing equipment of the organic fertilizer production line. 2. Compound fertilizer raw materials Basic chemical fertilizer powders such as urea, monoammonium phosphate, diammonium phosphate, potassium chloride, potassium sulfate, calcium magnesium phosphate fertilizer, bentonite, kaolin, etc. can process high, ...

Granulation is a core process in fertilizer production, turning powdered raw materials into uniform granules, improving fertilizer utilization, facilitating storage, and enabling mechanized fertilization. Based on production processes, raw material characteristics, and production capacity requirements, commonly used granulators in the fertilizer industry are mainly divided into four categories: disc granulators, rotary drum granulators, double roller press granulators, and flat die pellet machines. They are widely used in the production of various fertilizers such as organic fertilizers, compound fertilizers, and slow-release fertilizers. Disc granulator s are the mainstream equipment in small and medium-sized fertilizer production lines, with extremely high applicability. They rely on the centrifugal force generated by the rotation of an inclined disc to continuously roll and bind the powder into balls, achieving a granulation rate of over 90%. This equipment has a simple structure, i...

As a core piece of equipment in the production of compound fertilizer s and organic fertilizers, the rotary drum granulator is widely used in large-scale production due to its simple structure and high capacity. Its granulation effect directly depends on whether the material characteristics meet the standards. To ensure efficient and stable operation of the equipment and produce granules with uniform particle size and qualified strength, the material must meet four core requirements: particle size, moisture content, adhesiveness, and component compatibility. None of these can be neglected. A reasonable particle size distribution is the foundation of granulation. Rotary drum granulation relies on a "snowball" granulation principle, requiring a scientific ratio of coarse and fine materials. Fine powder (particle size ≤ 0.15mm) should account for 60%-70% to quickly absorb binders and form particle nuclei; coarse powder (particle size 0.15-0.5mm) should account for 30%-40% to fi...

Whether it is an organic fertilizer production line or a compound fertilizer production line, the granulation link is the key node that determines the product quality and production efficiency. With its unique design and excellent performance, the rotary drum granulator has become the core equipment of many fertilizer companies. It can improve the quality of finished fertilizer products from the root. When using wet granulation technology, the material is fully mixed, chemically reacted and mechanically extruded in the rotating cylinder to form particles of uniform size and within the ideal range. This kind of granules not only have high hardness and strong resistance to crushing, but are not easy to pulverize during transportation and storage, and the dissolution rate is controllable, which can meet the nutrient needs of different crops in different growth periods. The high balling rate means that the proportion of unqualified products is extremely low, and a small amount of return...

Huaqiang factory's fertilizer equipment drum granulator solves the problem of wall sticking. The fertilizer drum steam granulation manufacturing process has large output flexibility. Rotary drum granulator is cylindrical and has good heat preservation effect. The steam is used to increase the temperature of the material to meet the liquid phase required for granulation, which can greatly reduce The water content of the material during granulation reduces the load of the dryer and increases the output of the whole machine. Granulation mode of drum granulator The double roller granulator uses dry granulation, while the main working mode of drum granulator is wet granulation. After the basic fertilizer is humidified in the cylinder by a certain amount of water or steam or gas ammonia or phosphoric acid or nitrogen solution, the compound fertilizer production line of chemical reaction and heat supply or the cold granulation process with a small amount of water is added. Under th...
