Granular Triple Superphosphate (GTSP) Fertilizer Production Line (50,000-600,000 t/y)
Complete granular TSP fertilizer production system supporting acidulation-curing granulation or slurry granulation processes
- Production capacity: 50,000-600,000 t/y
- Product quality: Complies with GB 21634-2008 Granular Triple Superphosphate (GTSP)
Granular triple superphosphate is mainly produced using the following industrial methods: Acidulation-curing process, slurry process. The final product is predominantly supplied in granular form.
- Acidulation-Curing Process
- Slurry Granulation Process
The acidulation-curing process mainly consists of the following steps: mixing, acidulation reaction, solidification, cutting, curing, granulation, drying, cooling, screening, coating, packaging, and off-gas treatment.
- Wide adaptability to phosphate mineral, including mineral with relatively lower reactivity
- Longer reaction time enables a higher degree of phosphate rock decomposition
- Lower recycle ratio during granulation, reducing capital investment and energy consumption
Process limitation: Large curing warehouse area required

The slurry granulation process mainly consists of the following steps: mixing, neutralization reaction, slurry preparation, spray granulation, drying, cooling, screening, coating, packaging, and off-gas treatment.
- Allows the use of phosphoric acid with relatively lower concentration
- Enables extended slurry preparation time for more complete reaction and improved slurry fluidity
- No curing warehouse required
- Continuous production process
- Higher requirements for phosphate rock adaptability and phosphoric acid purity
- Larger recycle ratio compared with the acidulation-curing process
