Choosing the Right Liquid Fertilizer Production Line
How to Choose1
Size by capacity
Start from daily output of 12,000–24,000 L/day and annual tonnage up to 80,000 t/yr, then size vessels and the filling line to match.
2
Match chemistry and route
Decide solution versus suspension (suspension adds a bead-mill stage), and specify 316L, duplex or lined carbon steel from your fertilizer chemistry.
3
Choose packaging and control
Pick the filling module for packs, drums or IBC, and load formulations as PLC recipes for repeatable batches.

Process Engineering
Working Principle
- 1
A liquid fertiliser line dissolves and blends nutrients, chelates micronutrients and stabilises the solution or suspension before filtration and filling.
- 2
Raw materials are dosed into a jacketed vessel where temperature-controlled agitation completes dissolution; suspension grades require additional shear to keep solids dispersed.
- 3
Final filtration removes undissolved particles before filling into containers or IBC.

Equipment Guidance
Frequently Asked Questions
What equipment is included in a POLYC liquid fertilizer production line?
A POLYC liquid fertilizer production line covers the full process from raw-material storage and feeding, jacketed mixing and dissolving kettles, optional bead-mill grinding for suspensions, filtration, and automatic filling into packs, drums and IBC. POLYC supplies the complete line as one accountable package configured to your formulation, capacity and process.
Can the line produce both solution and suspension fertilizers?
Yes. The line is engineered for NPK nutrient solutions, chelated foliar feeds and micronutrient suspensions. Solution and chelate routes use jacketed dissolving and reaction kettles, while suspension concentrates add integrated bead-mill circulation grinding to keep insoluble solids stable and pourable.
Which materials are used for contact parts given fertilizer corrosion?
Fertilizer solutions are aggressive to standard stainless steel, so contact parts are specified as stainless steel 316L, duplex stainless or lined carbon steel matched to your chemistry. POLYC selects the material grade during line design rather than using one default for every product.
What capacity can POLYC configure for a liquid fertilizer line?
Designed output for mid- and large-scale operation is 12,000 to 24,000 liters per day, with overall line capacity configurable from 5,000 to 80,000 tonnes per year depending on vessel count and filling layout. Batch size ranges from 1,000 to 20,000 L per vessel.
How is grinding handled for suspension fertilizers?
For suspension concentrates the line integrates bead mills in a circulation grinding loop that reduces insoluble micronutrients and fillers to a fine, stable dispersion. This keeps the suspension homogeneous and prevents settling in storage and during filling.
Is the line modular and can modules be added later?
Yes. Every system module is optional and the line is configured from raw-material feeding, dissolving, grinding, filtration and filling according to your requirements. Additional vessels, a bead-mill stage or a second filling head can be added as capacity grows.
What filling and packaging options are available?
Filling is automatic for small packs, jerrycans, drums and IBC totes, with capping and labeling stations. The filling module is chosen to match your packaging mix so the line outputs retail packs and bulk containers on the same layout.
How is the production line controlled and are recipes managed?
The line runs on a PLC control system with recipe management, so each formulation is stored as a recipe covering dosing, dissolution temperature, grinding and filling setpoints. Operators load a recipe instead of re-entering parameters, which improves repeatability across batches.

What manufacturers say about working with POLYC MACHINE
These summaries reflect published application cases. Company names and roles are representative of the industries we serve.
“
The plaster and wall-material production line supplied by POLYC MACHINE integrated premixing, milling and transfer in one compact route. We reached consistent fineness across batches, and the local technical line made after-sales support responsive.
“
For our short gravure-ink runs, the small-batch grinding and dispersion route from POLYC MACHINE gave repeatable colour and fast changeover. The trial plan proposed before manufacture confirmed our fineness window without over-specifying the machine.
“
Our 1000L basket mill from POLYC MACHINE handles pigment and ink batches with the temperature control we needed for heat-sensitive formulations. Across multiple sites, the consistent basket-mill configuration simplified operator training and spare-parts planning.
