What are the main NPK liquid fertilizer manufacturing process?

Liquid NPK fertilizer is a type of fertilizer that contains three main nutrients: nitrogen (N), phosphorus (P), and potassium (K). The production process of liquid NPK fertilizer generally involves the following steps:

NPK Raw Material Preparation: Precise raw material preparation is the first step in making NPK liquid fertilizer. You can use either a static or dynamic batching system. Both feature multiple hoppers and precise discharge control. The batching system accurately measures and controls the N, P, K, and other materials within the same batch.
Raw Water Treatment: Clean water is essential for effectively dissolving NPK materials. To remove impurities and suspended particles, you should choose suitable water treatment equipment according to your budget. A simple water treatment system usually combines quartz sand and activated carbon filters. For a large-scale NPK liquid fertilizer plant,you can choose a reverse osmosis (RO) system with RO membranes (98% salt rejection, ≤5 μm precision) is recommended.
Dissolving NPK Raw Materials: After preparation, put the NPK raw materials into mixing tanks filled with water. With the built-in stirring and heating systems, the materials dissolve quickly. Continuous stirring prevents sedimentation, ensures uniform dissolution, and speeds up the process. The tank’s 304 stainless steel construction resists corrosion from chemical fertilizers, ensuring long-term durability.
Adding Chelating Agents and Additives: To improve nutrient stability and trace element availability, you can add chelating agents and other supplements using a stainless steel auxiliary ingredient tank.
Chelation Reaction Stage: Mix the raw material solution with additives in the reaction tanks. After about 12 hours, you will obtain the final NPK liquid fertilizer. Sau đó, store it in a white or stainless steel storage tank.
Packaging Final Liquid NPK Fertilizer: Cuối cùng, the finished NPK liquid fertilizer is transferred to the automatic liquid fertilizer filling system. It supports multiple container sizes such as 1L, 5L, and 20L.

When adding chelating agents, you can directly add liquid chelating agents to the batching tank. For powdered one, first mix them with water to achieve the desired ratio before adding them to the chelating tank.

What Is the Cost of an NPK Liquid Fertilizer Production Line and Expected ROI?

The investment in an NPK liquid fertilizer factory depends on its scale. Ví dụ, the 1000L/H NPK liquid fertilizer production line costs $21,000-$50,000; meanwhile, the large-scale NPK liquid fertilizer production project, with a capacity of 10-20 hours/hour, ranges from $200,000 ĐẾN $500,000. Đồng thời, you should also consider the cost of raw material, area, labor, etc... The ROI of starting an NPK liquid fertilizer business plan is attractive. Ví dụ, liquid NPK fertilizer usually sells for $200-$400 per ton, while raw material costs average $80-$120 per ton. A 5 T/H line running 8 hours per day produces about 40 tons daily. This gives a gross profit of $3,200-$12,800 per day. The payback period is often 6-18 months, depending on production scale, local market price, and labor cost. Nhận giải pháp

The choice of NPK liquid fertilizer production equipment mainly depends on your production capacity, raw material type, and investment budget. Below are two of YUSHUNXIN’s best-selling liquid NPK fertilizer manufacturing lines.

5 T/H NPK Liquid Fertilizer plant

các 5 T/H liquid NPK fertilizer production line is ideal for small to medium-scale fertilizer manufacturers who want to start quickly and make stable profits. With an estimated cost of around $100,000, this compact liquid fertilizer plant features a static batching machine, a 5 m³/h reverse osmosis (RO) system, a 2 m³ auxiliary material tank, a 6 m³ chelation reactor with temperature and mixing control, a 5 m³ finished product storage tank, and a semi-automatic filling machine. This setup ensures efficient nutrient blending, consistent product quality, and easy operation.
15 T/H Liquid NPK Fertilizer Manufacturing Process

các 15 T/H NPK liquid fertilizer production unit is designed for industrial-scale fertilizer plants aiming for continuous and high-output production. If you have access to your own mineral raw materials, this line offers a strong return on investment. It includes a Raymond mill (optional), a dynamic batching system, a bucket elevator, three 5 m³ raw material mixing tanks, three 5 m³ chelation reactors, three 2 m³ additive tanks, hai 10 m³ storage tanks, metering pumps, and a fully automatic filling line. Most customers also choose to equip large-scale liquid fertilizer production line with a PLC control system to minimize labor and reduce human error.

How to Customize an NPK Liquid Fertilizer Manufacturing Line for Different Formulations?

The NPK liquid fertilizer manufacturing line designed by YUSHUNXIN allows you to easily produce various liquid fertilizer formulations. An automated batching system is the core of this process. It includes multiple bins that precisely control the feeding rates of N, P, K and other materials. It helps you achieve customized NPK liquid fertilizers such as 3-1-2, 10-10-10, and 20-20-20 formulations. Ví dụ, in 2025, YUSHUNXIN assisted a client in Oman in building a 20-10-15 NPK liquid fertilizer plant. The main raw materials—urea, DAP, and MOP—were accurately dosed and mixed through our advanced liquid fertilizer production system.

Can I Convert Granular NPK into Liquid NPK Fertilizer?

Yes, you can easily convert granular NPK fertilizer into liquid NPK fertilizer. The key step is to install a fertilizer crusher before the automatic batching system. The crusher grinds NPK granules into fine powder, improving the dissolution rate in water and ensuring a stable liquid fertilizer formulation.

For small-scale NPK fertilizer granule crushing, we recommend you use a cage crusher. It is a medium-sized horizontal cage bars crusher, which can grind 4–10 tons/hour of NPK pellets.
For large-scale NPK liquid fertilizer manufacturing, a chain crusher is more suitable. With a capacity of up to 15 tons per hour, it comes in two models — single-rotor vertical chain crusher and double-rotor horizontal chain crusher. You can select the model based on your site layout and capacity needs.

Both machines integrate smoothly into a complete NPK liquid fertilizer production line and support continuous operation. This method helps you reuse existing NPK granules and upgrade your production without building a new system. By adding the right crusher, you can maximize raw material utilization, expand your fertilizer product range without building a new system.
