The 12 January 2026, a client of Senegal Multinational Fertilizer Company contacted us to study the implementation of an NPK fertilizer blending system of 100 TPH. “We are planning to launch a major NPK fertilizer plant in Senegal, with a capacity of approximately 100 TPH. We want to produce NPK fertilizer 10-20-10 from urea, de phosphate d’ammonium et de chlorure de potassium. Can you offer a turnkey solution of fertilizer mixing system with high formula accuracy and optimal anti-corrosion resistance? ? Please send me a quote. " Eventually, a stainless steel NPK granule mixing line 100 TPH was offered to him. Here are the specific details of our exchange regarding this project.

How to quickly produce mixed NPK fertilizer on a large scale ?
One of the key requirements of the Senegalese NPK fertilizer project was to produce blended NPK fertilizer in large volumes, with a maximum capacity of 100 TPH. To achieve this goal, the wisest choice is to purchase a fully automatic NPK fertilizer mixing system. Thanks to continuous operation including only dosing steps, mixing and bagging, this system makes it easy to accomplish commercial production of NPK fertilizers for global trade. In general, a bulk BB NPK fertilizer production line 100 TPH includes four fundamental units :
Dynamic dosing machine
The dynamic dosing machine continuously feeds the different NPK materials according to the programmed fertilizer formula, guaranteeing the accuracy of the nutrient ratio.
Rotary mixer BB model 2080
Designed specifically for large-scale production of blended NPK fertilizers, the BB drum mixer ensures homogeneous mixing of the N granules, P and K while preserving the intact shape of the particles. The model 2080 represents the best technical option for setting up an NPK mixing plant 100 TPH in Senegal.
Silo tampon
For large-scale production, it is recommended to add a buffer silo, which stabilizes the flow between mixing and bagging, reduces downtime, and maintains a continuous supply of the bagging station.
Double bucket bagging scale ×2
Regarding bagging in a large BB NPK fertilizer facility, the double output weighing equipment allows the finished fertilizer to be quickly bagged into bags of 20 has 50 kg. However, for exploitation of 100 TPH, two sets of double bucket scales are required to ensure the expected throughput.
What's more, the entire NPK fertilizer mixing system is controlled by a PLC controller, which limits the need to only two or three operators for feeding raw materials and bagging finished fertilizers.
Can the mixing system handle urea?, ammonium phosphate and potassium chloride for NPK 10-20-10 fertilizer ?
The Senegalese site wanted to prepare an NPK fertilizer 10-20-10 from urea, de phosphate d’ammonium, potassium chloride and other fillers, conditioning agents or trace elements. Two main points deserve particular attention :
Precise dosage of N‑P‑K elements according to the formula 10-20-10
Comme mentionné plus haut, producing an NPK fertilizer mixed with the required formula requires the use of a dynamic dosing machine. The equipment includes several weighing belts with variable frequency power supplies ; the system adjusts the flow rate of each material in real time based on the target formula. So, when making an NPK 10-20-10, the system calculates the mass flow of urea, du phosphate d’ammonium et du chlorure de potassium, then sets individual flow rates ensuring the right nutrient proportion. Because the NPK fertilizer mixing system works continuously and dynamically, the gap remains within an extremely narrow range, thus guaranteeing nutritional balance. What's more, the operator can save several recipes in the PLC ; change formula, for example from 10-20-10 to another type of NPK fertilizer, is done simply by selecting a different program, without additional mechanical adjustment.
Anti-corrosion customization of NPK fertilizer mixing system
The Senegalese factory located near the sea and using fertilizers containing chlorides such as KCl, the customer was very concerned about corrosion, machine downtime and the cost of replacing parts. To meet this requirement, we designed a stainless steel NPK pellet mixing line. All parts in contact with the products – the dynamic doser, the BB mixer drum, the buffer silo and the contact surfaces of the double scale – are made entirely of stainless steel. Thanks to this structure and a reinforced sealing system, NPK fertilizer mixing system effectively resists corrosion from fertilizer dust and salt air. So, the lifespan of the equipment increases significantly, while the internal surface remains smooth, reducing deposits and cross-contamination between different BB NPK fertilizer productions.
How Much Does Stainless Steel NPK Fertilizer Mixing System Cost? 100 TPH ?
In general, the cost of a complete stainless steel NPK fertilizer mixing system 100 TPH, for a project of this type, avoisine 580 000 USD. Since the Senegalese fertilizer manufacturer NPK confirmed the order and paid 50% deposit, we were able to give a 5% discount, bearing the final cost of the BB anticorrosion production line of 100 TPH is 551,000 USD.
