Wet granulation bonds fertilizer materials with water or binder at 20%–40% moisture, so particles stick, roll, and grow into stable granules. Crush long fibers first, then granulate and dry to lock strength. Choose it when you need round, strong pellets plus higher output and flexibility. And you can match it with batching, mixing, drying, cooling, screening, coating, and packing equipment.
What is the wet granulation process like?
Wet granulation process bonds materials with a liquid. And you should keep the feed moisture at 20%–40% to make granules form quickly and stay stable. This method suits powders, semi-dry mixes, and fibrous inputs like straw or rice husks. But for long fibers,you should crush them into small particles first, and then feed them into the granulator.
Once you feed the material and the it starts moving and tumbling inside the granulator, spray in water or a binder solution like molasses. The liquid coats each particle and forms liquid bridges, so particles begin to stick. After wetting, the rotating tooth shaft or drum body shears and mixes the wet mass. Meanwhile, particles collide, compact, and roll. And granules grow as they tumble and capture fines.
When wet granulation method is a better choice for you?
Are you troubled with whether wet granulation method fit for you or not? If you need strong, round fertilizer granules or high fertilizer output & flexibility, please choose wet fertilizer granulation method.
Equipment required for a wet fertilizer granulation method production line
Are you planning to build a wet fertilizer granulation production line? Still worrying about what equipment you need? Let’s take a look at the equipment required for the wet granulation process together. Equipment required for a wet fertilizer granulation method production line is usually arranged as: feeding & pre-treatment → batching and mixing → granulation & rounding → drying and cooling → screening and coating → packing and palletizing.
For an organic fertilizer wet granulation line, the typical equipment is: Loader feeding machine → Vertical crusher → Rotary drum screening machine → Dynamic automatic batching system → Organic fertilizer granulator → Organic fertilizer rounding machine → Rotary dryer → Rotary cooler → Cyclone dust collector → Rotary drum screening machine → Coating machine → Single-bucket packing machine → Palletizer. This configuration ensures stable dosing, uniform granules, and cleaner production.
For compound fertilizer granulation, a drum wet granulation line can be: Dynamic feeding machine → Double-shaft horizontal mixer → Rotary drum granulator → Rotary drum screening machine → Rotary dryer → Rotary cooler → Coating machine → Packing machine. Conveyors and dust collection can be added between sections to improve efficiency and site cleanliness.
