In the granulation stage of organic fertilizer production, traditional processes often require materials to undergo multiple steps: “pre-drying → crushing → conditioning → granulation.” This results in long process flows, high energy consumption, and significant equipment investment. A groundbreaking integrated solution has emerged—the new type two-in-one organic fertilizer granulator. It innovatively combines the two core processes of crushing and granulation into one machine. Like a highly efficient “Transformer,” it directly converts semi-wet composted material into uniform granules,completely reshaping the granulation path for organic fertilizer.

Core Advantages: A Revolution in Integration, Efficiency & Low Consumption

The revolutionary core of this equipment lies in its structural innovation. Through a two-stage functional design within a single rotor, it achieves the ultimate compression of the process flow.

Disruptive Process Integration
The machine features an integrated composite rotor. The front section is a high-speed crushing zone equipped with heavy-duty hammers or blades that powerfully break up and preliminarily crush the incoming semi-wet compost. The material then immediately enters the rear granulation and forming zone. Through unique centrifugal throwing, friction rolling, or light compaction, this zone agglomerates the now suitably fine and moist material into balls. One machine replaces the traditional “crusher + granulator” combination, drastically shortening the process flow and reducing material transfer points and dust sources.

Exceptional Direct-Handling Capability for Semi-Wet Materials
Designed specifically for post-compost organic matter with 20%-35% moisture content. It requires no additional drying of the material. Its front-end crushing function effectively handles fibrous lumps that may exist in the compost, while the granulation section makes full use of the material’s inherent stickiness and the cross-linking action of microbial mycelia to promote pellet formation. This not only significantly reduces thermal energy consumption but also better preserves organic matter activity and nutrients.

High Pelletizing Rate & Flexible Particle Control
By adjusting rotor speed, internal screen gap, or adding trace amounts of liquid bio-binders, the particle size (e.g., 2-8mm) and density can be controlled within a certain range. The optimized fluid dynamics design ensures a high initial balling rate, producing granules with a relatively smooth surface and moderate hardness, which is beneficial for subsequent low-temperature drying and screening.

Synergistic Production: The Simplified “Core Hub” of Organic Fertilizer Production

The advent of the two-in-one granulator makes the layout of organic fertilizer production lines more compact and efficient, serving as the core hub connecting composting and drying.

Direct Interface with “Composting Process”: It can receive basically matured material processed by a hydraulic compost turner or briefly cured organic fertilizer raw material, achieving “granulation right out of the trench,” greatly enhancing production fluency.

Optimizing the “Drying & Cooling” Stage: The produced moist pellets have uniform strength and can directly enter a low-temperature drum fertilizer dryer and cooler. Their uniform size distribution facilitates more efficient and even heat exchange and cooling.

Simplifying the “Screening & Recycle System”: After granulation and screening, fines can be directly returned to the machine’s feed inlet through a designed channel, creating an internal short-cycle and reducing the need for external conveying equipment, resulting in a simpler system.

Reducing Overall Investment & Operating Costs: It saves the investment for a separate crusher, related conveyors, and their foundations. It also reduces floor space, power consumption, and daily maintenance points, offering significant comprehensive benefits.

Evolution & Outlook: A Smarter, Greener Integrated Granulation Center

With technological iteration, the two-in-one granulator is evolving towards adaptive control and resource-efficient utilization.

Intelligent Sensing & Adaptive Adjustment: Integration of moisture sensors and torque monitoring allows for automatic adjustment of rotor speed and internal gaps based on real-time feed moisture and resistance, enabling one-touch adaptive production and ensuring stable granule quality.

Precision Binder Spraying System: Integrated high-atomization nozzles and flow meters allow for precise addition of trace liquid binders or functional microbial solutions based on material properties, achieving simultaneous enhanced granulation and functional modification.

Modular Design & Multi-Function Expansion: By changing the rotor’s functional modules (e.g., replacing the granulation section with a polishing section), its functionality can be expanded to achieve multiple functions in one machine, meeting market demands for different product forms.
