Fertilizer Granulator Machines: Transforming Compost Powder into Premium Pelleted Fertilizer

Published on: 2026-10-13

Fertilizer granulator machines serve as the core forming equipment in organic and compound fertilizer production lines, turning loose compost powder, livestock manure powder, humic acid and NPK mixed raw materials into uniform solid fertilizer pellets. As a professional fertilizer equipment manufacturer, we supply standalone granulators and customized complete granulation solutions for fertilizer plants, large farms and waste recycling enterprises.

Compared with loose powder fertilizer, pelleted fertilizer has obvious advantages: less dust during packaging and application, slow nutrient release, better storage resistance and convenient mechanical spreading. Our granulation equipment can realize continuous pellet forming, improve fertilizer commercial value, and help customers upgrade from simple compost powder to marketable granular fertilizer products.


Main Fertilizer Granulator Models

Equipment Type            Core Features            Suitable Scenarios            
Disc / Pan Granulator            Adjustable disc inclination angle and rotating speed; granulation rate over 90%; round and smooth pellets; low energy consumption, simple operation. Hourly output: 1–10 tons.            Small & medium fertilizer factories, organic compost projects, low investment budget, produce spherical organic fertilizer            
Rotary Drum Granulator            Continuous large-capacity wet granulation; steam heating & humidification inside drum; strong material adaptability, stable granulation quality. Output up to 15–30 tons per hour.            Large-scale compound fertilizer / NPK production line, high-volume continuous manufacturing            
Double Roller Extrusion Granulator            Dry granulation at room temperature, no need for drying system; no binder required; high pellet hardness, low breakage rate.            Projects limited by drying cost, produce humic acid, compound fertilizer, low moisture raw materials            


Auxiliary Supporting Granulation System

1. Drying & Cooling Machine

After wet granulation, fresh pellets carry high moisture. Rotary dryer and cooler reduce pellet moisture rapidly, improve hardness, and prevent sticking during storage. It is essential supporting equipment for disc and drum wet granulation lines.

2. Fertilizer Coating Machine

Coating equipment wraps a protective layer on fertilizer pellets to prevent caking, control nutrient slow release, and improve surface appearance. Widely used for high-grade compound and slow-release fertilizer.

3. Rotary Screener

Sieves finished pellets, separate oversized and undersized particles. Unqualified materials return to the granulator for re-granulation, improving finished product yield.


Overall Advantages of Complete Fertilizer Granulation System

1. Wide Raw Material Adaptability

It can handle composted manure, straw compost, sludge, humic acid, NPK powder, and other mixed materials, supporting both organic fertilizer and compound fertilizer production.

2. High Granulation Rate & Stable Pellet Quality

Precise control over material moisture, rotating speed, and feeding volume; finished granules have uniform size, high strength, and low powder rate, meeting commercial fertilizer market standards.

3. Flexible Production Capacity

Modular design. Customers can choose small standalone granulator or full automatic production line according to annual output target, from 1 ton/h small workshop to 30 ton/h large factory.

4. Energy Saving & Simple Maintenance

Key parts use wear-resistant materials. Rollers, lining and blades are easy to replace. Dry extrusion granulation cuts energy costs by removing the drying procedure.

5. High Commercial Value of Final Products

Granular fertilizer is easier to package, transport, and apply. The slow-release effect reduces nutrient loss, helping customers get a higher selling price than powder compost.

6. Customized Technical Support

We provide layout design, formula guidance, equipment installation training and after-sales service, one-stop solution for fertilizer plant construction.


Conclusion

Powder compost has limited market competitiveness. A reliable fertilizer granulator system converts compost into high-value granular fertilizer, realizing the full industrial chain from organic waste fermentation to finished fertilizer pellets. Whether you plan to build a small organic fertilizer workshop or a large NPK compound fertilizer factory, we can match suitable granulation equipment and a process scheme to your raw materials and capacity requirements.
