Monoammonium phosphate (MAP) is one of the most efficient carriers of phosphorus and nitrogen. This is a nutrient-dense fertilizer which delivers balanced nitrogen (N) and phosphorus (P₂O₅) for robust crop growth. Its water-soluble properties and high nutrient concentration make it a preferred choice for bulk blending and direct soil application. However, the physical form of MAP dramatically impacts storage, handling, and field performance. Dusty powder causes substantial nutrient loss and application unevenness; good quality granules, on the other hand, distribute the nutrient evenly and prevent nutrient loss. For investors, a turnkey map granulator machine solution for fertilizer project is the fastest path to operational success.
A turnkey map granulator machine solution for fertilizer project from LANE Heavy Industry Machinery offers a seamless, efficient, and scalable path from concept to full operation. We offer a flexible capacity range from 1–20 TPH. Our integrated solutions eliminate project fragmentation, reduce startup timelines, and ensure stable, high-quality MAP granule production.
MAP is water-soluble and provides a quick-release form of phosphorus that is essential for root development, flowering, and early plant growth. MAP (11-52-0) provides a high concentration of phosphorus along with a moderate amount of nitrogen, making it ideal for starter fertilizers and crops that require strong early root establishment. Its low hygroscopicity and excellent storage properties make it suitable for bulk blending, direct application, and use as a raw material in compound NPK fertilizers.
The production of high-quality MAP granules is a complex process that begins with the controlled reaction of ammonia and phosphoric acid to form a MAP slurry, followed by granulation, drying, cooling, screening, and packaging. A complete turnkey map granulator machine solution for fertilizer project must integrate all these stages seamlessly, ensuring consistent product quality and maximum operational efficiency. LANE Heavy Industry has over 20 years of engineering experience in designing such integrated systems, which makes us a trusted partner for MAP fertilizer manufacturers worldwide.
Establishing a new MAP fertilizer production line or upgrading an existing facility involves significant capital investment and technical complexity. A turnkey map granulator machine solution for fertilizer project from LANE Heavy Industry eliminates the risks and coordination challenges of piecing together equipment from multiple suppliers. The customer receives a fully integrated production line. We provide:
This end-to-end service removes the guesswork from setting up a new MAP line or upgrading an existing one and significantly shortens the project timeline.
A complete turnkey map granulator machine solution for fertilizer project from LANE Heavy Industry integrates approximately 12 key equipment systems, each optimized for MAP production.
Ammoniation Reactor
The heart of the MAP production line is the ammoniation stage, where phosphoric acid reacts with ammonia under controlled conditions. LANE’s reactors maintain reaction times of just 3–5 seconds while ensuring stable operation even during high-throughput production. This controlled reaction forms a uniform MAP slurry with the correct N–P balance, which is critical for granulation quality.
3.3 Granulation – The Core Step
At the center of every turnkey map granulator machine solution for fertilizer project, LANE offers three granulator types to suit different capacity bands, feedstock conditions, production process, and budget levels:
| Granulator type | Best for | capacity range |
| Rotary Drum Granulator | Large scale continuous production; wet granulation | 2–20 TPH |
| Disc Granulator | Small to medium scale lines; open operation and easy observation | 1–10 TPH |
| Double Roller Extrusion Granulator | Dry granulation; no drying step required; lower energy consumption. Best for powdered granulation. | 1–8 TPH |
The rotary drum granulator is the preferred choice for high capacity turnkey map granulator machine solution for fertilizer project. It delivers stable, strong, and uniformly sized granules (typically 2–4 mm) with a granulation yield of 92–95%. The slurry generated during the ammoniation reaction coats recycled seed material inside the drum, building dense layers that improve product hardness.
Fresh granules leaving the granulator contain 10–12% moisture. LANE uses a rotary drum dryer, heated by a hot blast stove (gas, coal, diesel, or biomass), to bring the moisture down to 2–3%. Immediately afterwards, a rotary cooler reduces the granule temperature to near ambient levels. This process prevents caking and preserves nutrient integrity.
3.5 Screening, Coating, and Packaging
The final stages of LANE’s turnkey map granulator machine solution for fertilizer project include multi-layer vibrating screens for particle size classification. The off-spec particles are sent to a crushing machine and recycled back to the granulator. The on-spec granules are sent to the rotary coating machines for controlled-release coating; after coating, the granules are sent to the automated packaging systems that ensure accurate weighing and durable packaging for market distribution.
LANE’s turnkey map granulator machine solution for fertilizer project is not “one size fits all.” The company engineers production lines for specific throughput requirements:
| Capacity range | Line characteristics | Suitable for |
| 1–3 TPH | Compact layout; disc granulator or double roller press; minimal civil works | Startups, pilot plants, small regional producers |
| 3–8 TPH | Medium footprint; rotary drum or double roller granulator; fully automated batching and packing | Established companies expanding into MAP |
| 8–20 TPH | Full scale industrial plant; large rotary drum granulator; advanced PLC automation; heat recovery drying system | Large fertilizer groups and export-oriented producers |
All production lines can be tailored to the customer’s available factory dimensions, utility infrastructure, and fuel preference.
Every machine in a turnkey map granulator machine solution for fertilizer project is manufactured under an ISO9001 certified quality system and can be supplied with international certifications (SGS, BV, EU, CE) as required. We have already exported complete fertilizer plants to more than 50 countries, including the United States, Canada, Russia, Turkey, Indonesia, Mexico, India, and Brazil.
