Double Roller Granulator For Compound Fertilizer Production

Product Introduction:
Our double roller granulator is a professional compaction granulation machine designed for producing high-quality compound fertilizer granules without liquid binders. Utilizing advanced dry granulation technology, it transforms powder materials into uniform, dense granules through mechanical pressure.

Working Principle:

1. Powder materials are fed between two counter-rotating rollers

2. High mechanical pressure (50-100MPa) compacts materials

3. Compacted flakes are broken into uniform granules

4. Final granules are screened and polished

Material Compatibility:
✓ NPK compound fertilizers
✓ Potassium fertilizers (SOP/MOP)
✓ DAP/MAP fertilizers
✓ Specialty fertilizer blends
✓ Mineral powders

Advantages Over Wet Granulation:

• 30% lower energy consumption

• No drying process required

• Higher nutrient concentration in final product

• Easier formula adjustments

• Lower maintenance requirements
