How Are Perfect Fertilizer Granules Made? The Magic of Compaction!

 Have you ever wondered how small, uniform fertilizer granules are produced? The secret lies in an efficient process known as fertilizer granules compaction. With the ability to incorporate over 20 different materials—including essential trace elements like boron, iron, copper, zinc, and manganese—this method is both versatile and efficient.

1. Storage and Precise Measurement

Raw materials such as urea, ammonium phosphate, and potassium chloride are elevated and conveyed into storage bins. The complexity of the mixing system depends on the fertilizer formula, but accuracy is always key.

2. The Heart of the Process: Compaction

This is where the real magic happens. A specialized fertilizer compaction machine, also known as a roller press granulator, exerts tremendous pressure on the mixed powder. As the material passes between two counter-rotating rollers, it’s compressed into a solid plate. The pressure builds, then releases, forming dense sheets ready for the next stage.

3. Crushing and Sizing

The compacted plates are pre-crushed and screened into desired particle sizes. Fine particles are recycled back into the mix, while oversized granules are crushed again. Proper selection of crushers and screens is crucial for economic efficiency.

4. Polishing and Anti-Caking Treatment

Finally, the granules are polished in a rotating drum to smooth edges. Anti-dust and anti-caking agents are added to ensure a clean, free-flowing final product. The result? High-quality, uniform fertilizer granules ranging between 1-4mm.

For single-component fertilizers like granular potassium or ammonium sulfate, the process is even simpler—requiring less equipment and lower investment. Thanks to the efficiency of the fertilizer compaction machine, producing high-quality granules has never been easier!

Revolutionary Working Principle

The essence of the roller compaction granulator lies in its ingenious design – two identical rollers rotating in opposite directions at the same speed. When precisely proportioned raw materials are forced into the roller gap, the magic begins: tremendous pressure expels air from the material, reduces particle spacing, enhances intermolecular forces, and ultimately forms dense flakes or strips.

Notably, the pressure variation follows an exact pattern: peaking at the horizontal position of the rollers (often reaching several megapascals), then rapidly decreasing. This intelligent pressure regulation ensures the formed material can perfectly detach from the roller surface through its own elasticity, ready for subsequent processes.

Unparalleled Energy Efficiency

Compared to traditional wet granulation, roller compaction technology represents a quantum leap. It completely eliminates the energy-intensive drying process, reducing energy consumption by 50%-70%! This means not only significant cost savings but also respect for Earth’s resources.

Fertilizer Processing Process with a Disc Granulator

The disc granulator is the core equipment in a fertilizer production line, and its standardized processing flow is crucial for producing high-quality fertilizer.

The first step is raw material preparation. Raw materials include organic materials such as animal manure and plant residues, as well as inorganic materials such as urea and ammonium phosphate. These raw materials must be crushed to reduce particle size for subsequent mixing and granulation. Furthermore, they must be accurately weighed according to the formula to ensure an accurate nutrient ratio, and the humidity must be adjusted to 20%-30% to facilitate granule formation.

The second step is raw material loading. The disc is driven by a motor, and the speed can be set according to the raw material characteristics and the desired particle size. The raw material is evenly distributed on the disc, spread toward the edges due to centrifugal force, and then rises along the inner wall due to friction. After reaching a certain height, it falls back due to gravity, forming a circular motion.

The third step is the application of a binder. As the raw materials circulate, a nozzle above the disc sprays the binder onto the raw materials. The binder is usually a natural polymer or inorganic substance. When it comes into contact with water, it develops viscosity, causing the fine particles to bind together. The spraying rate must be precisely controlled: too much will result in oversized and dense granules, while too little will make them difficult to form.

The fourth step is granule growth. As the disc rotates continuously, the already bonded small granules continuously absorb the raw materials, growing larger as they rotate. The collision and friction between the granules also make them more compact. The operator must observe the granule state and adjust the rotation speed and tilt angle promptly. The rotation speed affects the residence time and granule size, while the tilt angle changes the movement trajectory and helps shape the granules.

The fifth step is discharge. When the granules reach the desired size and quality, they overflow from the edge of the disc. Freshly formed granules contain moisture, which requires drying to reduce the moisture content and improve stability and storage performance.

Through this series of rigorous processes, the disc granulator machine transforms various raw materials into high-quality granular fertilizers, providing strong support for agricultural production.
