Have you ever looked at a sprawling cornfield and wondered what makes those plants grow so tall and green? Often, the secret is a high-quality fertilizer known as DAP. To create this essential nutrient source, one must master the industrial production process of Diammonium Phosphate. It is a journey that combines complex chemistry with heavy-duty mechanical engineering.
At our company, we have spent more than 20 years focusing on the Chinese fertilizer machinery manufacturing sector. We don’t just build machines; we design the heartbeat of agricultural success. For us, the industrial production process of Diammonium Phosphate is an art form that we have perfected over two decades of dedicated industry experience.
The basic chemistry of DAP involves the reaction between phosphoric acid and ammonia. However, the real challenge lies in scaling this up for a global market. The industrial production process of Diammonium Phosphate must be stable, efficient, and cost-effective.
The Reaction Stage: Pre-Neutralizer and Pipe Reactor
Everything begins with the neutralization reaction. In a professional industrial production process of Diammonium Phosphate, we use specialized stainless steel pre-neutralizers or pipe reactors. These vessels handle the high temperatures generated when ammonia meets phosphoric acid. Our engineering team uses acid-resistant materials to ensure these components last for years, even under the most corrosive conditions.

The Heart of the Line: Double Roller Extrusion Granulator
While traditional methods often use rotary drums, many modern facilities are shifting toward the Double Roller Extrusion Granulator for specific DAP formulations. This machine is a game-changer in the industrial production process of Diammonium Phosphate.

Why do we recommend the double roller granulator?
No Drying Required: This is a dry-type granulation process. Because it uses mechanical pressure to form granules, you save a massive amount of energy that would otherwise be spent on large drying furnaces. This is a massive leap forward in the industrial production process of Diammonium Phosphate.
High Strength: The rollers exert immense pressure, creating DAP granules that are incredibly hard and resistant to breaking during transport.
Room Temperature Operation: It simplifies the industrial production process of Diammonium Phosphate by operating at ambient temperatures, reducing the thermal stress on your factory environment.
Supporting Machinery: Belt conveyors and Crushers
To keep the industrial production process of Diammonium Phosphate moving, we utilize heavy-duty belt conveyors to transport materials between stages. If any granules don’t meet the size requirements, our Chain Crushers quickly break them down so they can be re-processed. This “closed-loop” system ensures that there is zero waste in your production cycle.
In a modern facility, the industrial production process of Diammonium Phosphate doesn’t end with granulation. To ensure the final product is marketable, we integrate advanced cooling and screening systems. Our Rotary Cooling Machines reduce the temperature of the granules immediately after extrusion, which prevents the DAP from clumping during storage.
Furthermore, the precision of the industrial production process of Diammonium Phosphate is maintained by our high-frequency vibrating screeners. These screens ensure that only granules within the 2mm to 4mm range reach the packaging station. By maintaining such strict control over the physical properties of the fertilizer, we help our clients build a brand reputation for quality and reliability in the global marketplace.
Building a factory for the industrial production process of Diammonium Phosphate is a major investment. You need a partner who understands every bolt and every chemical reaction.
