Product Overview
As a leading supplier of fertilizer equipment, we provide advanced and efficient organic compound fertilizer granulation production lines. These lines are designed to transform raw organic materials—such as livestock manure, agricultural waste, and bio-organic substances—into uniform, high-quality granules. Our solutions are ideal for large-scale production of organic and bio-organic compound fertilizers, supporting sustainable agriculture and circular economy practices.
Key Features & Advantages
1. High Granulation Rate – Utilizes specialized granulation technology to ensure high yield and uniform particle size.
2. Flexibility – Compatible with various organic raw materials and adjustable to meet different nutrient content requirements.
3. Eco-Friendly Design – Minimizes dust emissions, reduces energy consumption, and supports green production.
4. Durability & Reliability – Equipment is built with robust materials and designed for continuous, stable operation.
5. Automation Control – Equipped with PLC-based control systems for easy operation and consistent product quality.
Working Process
1. Raw Material Pre-processing
Crushing, screening, and mixing of organic materials to achieve proper consistency and nutrient balance.
2. Fermentation (Optional)
For bio-organic fertilizers, aerobic fermentation is conducted to stabilize organic matter and enrich microbial content.
3. Granulation
The core stage where materials are formed into granules using one of the following granulation devices:
Disc Granulator – Uses a rotating inclined disc to form uniform spherical granules.
Double Roller Extrusion Granulator – Compresses materials into granules through mechanical extrusion, suitable for dry granulation.
Drum Granulator – Agglomerates materials in a rotating drum, ideal for large-output production.
Dental Granulator (or Stirring Tooth Granulator) – Utilizes high-speed stirring and cutting to create granules, suitable for wet materials.
2-in-1 Granulator – Combines mixing and granulating functions in one unit, saving space and energy.
Flat Die Granulator – Extrudes materials through a flat die to produce cylindrical granules, often used for small to medium-scale production.

5. Screening & Coating – Separates undersized and oversized particles, and applies coating agents to improve quality.
6. Packaging – Automated weighing and packaging for final products.
