Product Description

The dry powder fertilizer granulator can directly extrude powdered fertilizer raw materials into granules at room temperature. Its core adopts a double roller extrusion granulation process. The entire procedure requires no water or additives, and no drying equipment is needed. The resulting granules are uniform in size, highly dense and resistant to breakage. Offering excellent value for money, featuring low noise levels, a long service life, simple operation and low running costs, this equipment delivers significant economic benefits and is the ideal choice for small, medium and large-scale fertilizer granulation plants.

Product Advantages:

1. No drying required: Utilizing advanced double-roller extrusion technology, this process directly converts powdered raw materials into granules, completely eliminating the need for the drying and cooling systems required in traditional processes.
2. Preservation of nutrients: The entire process takes place at room temperature, preventing the degradation of heat-sensitive components, ensuring that nutrients are fully retained and maintaining the stability of the fertilizer’s efficacy.
3. Lower investment costs: The process features a short workflow, requires minimal floor space, and offers convenient daily operation, enabling “one-stop” automated production from feedstock input to final output.
4. High-performance wear-resistant roll liners: The roll liners withstand heavy loads and wear, and can handle high-frequency continuous operation without jamming, overheating, or frequent breakdowns.

Working Principle

This series of roller granulation belongs to extrusion sliding model, whose working principle is: the belt and belt pulley are driven by an electric motor, and transmitted to the drive shaft by reducer, and work in the same direction through the open gear and the passive shaft.The material is added from the feed hopper, extruded by the roller, demoded and pelleted, and passed through a pair of chains to the crushing screen studio, where the finished product pellets (balls) are screened and separated, and then the material is returned and mixed with new materials for granulation.With the continuous rotation of the motor and the continuous entry of materials, mass production can be realized.
