MAP / DAP Production Facility
Delivering turnkey solutions that ensure optimal production of Monoammonium Phosphate (MAP) and Diammonium Phosphate (DAP).
We provide everything from initial design to full-scale operation, ensuring that your production line runs smoothly and delivers top-quality fertilizers consistently.
Step 1: Raw Material Preparation
- Ammonia Storage and Handling System
- Phosphoric Acid Storage and Handling System
- Pre-Reaction Mixing Equipment
Step 2: Reaction
- Continuous Stirred-Tank Reactor (CSTR)
- Pipe Reactor (Optional)
- For MAP: The reaction typically follows:
- For DAP: The reaction is:
Step 3: Granulation
Granulation Technology:
- The slurry from the reactor is fed directly into a granulator, such as a rotary drum granulator, where it coats seed particles or nuclei.
- The rotation of the drum and the cascading motion of the material inside promote granule formation and ensure that the granules achieve the desired size and shape.
Step 4: Drying and Cooling
- The granules produced from the slurry are typically dried in a rotary dryer.
- After drying, the granules are cooled in a cooler, often a rotary or fluidized-bed cooler, to stabilize the product and prepare it for screening and storage.
Step 5: Screening and Milling
- Multi-stage screening systems that allow for the classification of granules into different size categories.
- crushing systems to break down oversized granules into smaller particles, which are then reintroduced into the granulation process.
