Light Calcium & High-Phosphorus Soil Granulation Production Line Fertilizer Pelletizing Solution

Light calcium carbonate (CaCO₃) and high-phosphorus soil are widely used as soil conditioners and phosphatic fertilizers in modern agriculture. However, their powdery form often leads to poor flowability, dust issues, and uneven application.

To solve these challenges and enhance fertilizer value, Gofine offers a complete light calcium and high-phosphorus soil granulation production line—designed to convert loose powder materials into uniform, dust-free granules suitable for large-scale application and commercial distribution.

What Is Light Calcium and High-Phosphorus Fertilizer?
Light calcium carbonate (precipitated calcium carbonate): Improves soil pH, supplies calcium, enhances nutrient absorption.
High-phosphorus soil (phosphate-rich clay/mineral): Provides slow-release phosphorus and improves soil fertility.
When granulated together or separately, these materials become more effective, easier to handle, and more environmentally friendly.

Raw Materials Suitable for This Granulation Line
Light calcium carbonate (PCC)
High-phosphorus soil / phosphate rock powder
Calcium magnesium phosphate
Phosphogypsum
Bentonite clay (as binder)
Urea, ammonium phosphate (optional for NPK blending)
Humic acid, zeolite, or trace elements (nutrient enhancement)

Recommended Granulation Equipment
To process high-phosphorus and calcium-based powder, we recommend the following granulators:

1. Double Roller Extrusion Granulator (Dry Granulation)
No drying required
Ideal for moisture-sensitive calcium materials
Granules: oval or pillow shape (2–6 mm)
Compact structure and low energy consumption
2. Rotary Drum Granulator (Wet Granulation)
For large-capacity NPK + Ca blending
Can process phosphate and calcium with liquid binder
Spherical granules, smooth surface
3. Disc Granulator
Suitable for fine calcium/phosphate powders
Moisture content: 20%–35%
Uniform round granules (3–8 mm)

Complete Granulation Production Line Configuration
A full light calcium + phosphorus fertilizer production line includes:
Raw Material Crushing: Chain crusher or hammer mill
Weighing & Batching: Automatic batching system
