NPK Compound Fertilizer Production Line/ Fertilizer Manufacturing Plant
This Rotary Drum Granulation production line is equipped with a static batching machine, double-shaft mixer, rotary drum granulator, chain crusher, rotary drum dryer & cooler, rotary drum screening machine, and other auxiliary fertilizer equipment. The annual output can be 30,000 tons. As a professional fertilizer production line manufacturer, we also supply the customers with other granulation lines with different production capacity, such as 20,000 T/Y, 50,000T/Y, 100,000T/Y, etc.
1. Adopts advanced rotary drum granulator, the granulation rate can reach 70%.
2. Key parts adopt wear-resistant and corrosion-resistant materials, and the equipment has a long service life.
3. Adopt plastic plate or stainless steel plate lining, materials not easy to stick on the inner wall of the machine.
4. Stable operation, easy maintenance, high efficiency, and low energy consumption.
5. Adopt belt conveyor to connect the whole line, realizing continuous production.
6. Adopt two sets of dust settling chamber to deal with the tail gas, environment friendly.
7. Two times screening process ensure qualified granules with uniform size.
8. Evenly mixing, drying, cooling, and coating, the finished product has superior quality.

1. Raw materials batching
According to market demand and local soil determination results, raw materials such as urea, ammonium nitrate, ammonium chloride, ammonium sulphate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, general calcium) and potassium chloride (potassium sulphate) shall be allocated in a certain proportion. The additives and trace elements are weighed by the belt scale and proportioned to a certain proportion. According to the formula ratio, all the raw materials are evenly mixed by the mixer. This process is called premix. It ensures accurate formulation and enables efficient and continuous batching.
Fully mix the prepared raw materials and stir them evenly, which lays a foundation for efficient and high-quality granular
fertilizer. Horizontal mixer or disc mixer can be used for even mixing.
3. Materials Granulating
After crushing, materials are transported into rotary drum granulator by belt conveyor. With the constant rotating of drum, the materials form a rolling bed, and moves along a certain path. Under the extrusion force produced, the materials agglomerate into small particles, which become the core, attaching the powder around to form the qualified spherical granules.
4. Fertilizer Drying
Material shall be dried after granulating to reach the water content standard. When the dryer is rotating, a series of internal
fins will lift the material by lining the inner wall of the dryer. When the material reaches certain height to roll the fins back,
it will be fell back to the bottom of the dryer, then passing through the hot gas stream as it falls. Independent air hating
system, centralize waste discharge result in energy and cost saving.
5. Fertilizer Cooling
Rotary drum cooler removes fertilizer water and lowers temperature, used with rotary dryer in organic fertilizer and in-organic fertilizer production, which greatly increases cooling speed, and relieves work intensification. The rotary cooler also can be used to cool other powdered & granular materials.
6. Fertilizer screeningAfter cooling, all unqualified granules are screened out through the rotary screening machine and
transported by the belt conveyor to the mixer and then mixed with the other raw materials for reprocessing. The finished products will be transported to the compound fertilizer coating machine.
It is mainly used to coat the surface of quasi-granules with a uniform protective film to effectively extend the preservation
period and make granules smoother. After coating, here come to the last process - packaging.
Automatic quantitative packaging machine is adopted in this process. The machine is composed of an automatic weighing and packing machine, conveying systems, sealing machines, and so on. Hopper can also be configured according to customer requirements. Quantitative packaging of bulk materials such as organic fertilizer and compound fertilizer has been widely used in different industries and fields.
