Double Roller Granulator – High-Efficiency Fertilizer Granulation

As the core equipment for compound fertilizer production, our double roller granulator utilizes an advanced dry extrusion process to form uniform fertilizer granules (2.5–20mm) in a single step.

Key Features:

✔ High Granulation Rate (≥95%) – Ensures maximum material utilization with minimal waste.
✔ Customizable Roller Design – The ball socket shape and size on the roller shell can be tailored to meet specific requirements.
✔ No Drying Needed – Directly compacts raw materials into dense, spherical pellets, ideal for compound fertilizer production.
✔ Energy-Efficient & Eco-Friendly – Operates without binders or drying systems, reducing energy consumption and costs.

Ideal for large-scale fertilizer manufacturing, this granulator delivers high output, consistent particle size, and low maintenance—making it a top choice for modern fertilizer plants.
