Fertilizer Granulator Machine with Wide Raw Material Adaptability and No Binder Required for Adjustable Pellet Size Dry Granulation

The double roller extrusion granulator uses dry granulation technology to form fertilizer pellets at normal temperature — without drying or adding binders. It is widely used for granulating NPK compound fertilizer, humic acid fertilizer, organic fertilizer powder, and other chemical raw materials. The machine integrates with a complete fertilizer production line, and pellet size and shape can be adjusted by replacing the roller skins. It is a cost-effective core granulation solution for small and medium fertilizer factories.

1. Dry granulation at room temperature — no dryer required, greatly reducing energy consumption and factory investment.
2. No binder needed; finished pellets have high hardness, resist breakage, and are convenient for storage and transportation.
3. Wide raw material adaptability — suitable for compound fertilizer, humic acid, mineral powder, and other powder materials.
4. Compact structure, small footprint, simple operation, and low failure rate.
5. Granulation rate of 90% and above, with stable output and adjustable pellet size.
6. Easy roller skin replacement, with support for customized pellet shapes and specifications.
7. Equipped with overload protection to effectively prevent hard impurities from damaging the rollers.

• Humic acid fertilizer and mineral fertilizer granulation
• Organic fertilizer powder granulation
• Chemical powder and feed additive granulation
• Small and medium fertilizer processing plants

Uniform powder raw materials are fed into the gap between two counter-rotating rollers. Under high-pressure extrusion, the powder is pressed into pellets through the cavities on the roller surface. The formed pellets are discharged directly — no drying or cooling procedures are required.
