Why the project happened
A trader importing fertilizer components wanted to launch local NPK blends with fast turnaround, multiple seasonal formulas, and low capital risk. They chose a BB line because it could start producing within months at a fraction of a granulation plant's cost.
What the customer faced
These are the specific issues the project was built to solve.
- Imported finished NPK was expensive and tied up working capital
- Seasonal demand required quick formula changes between regions
- Manual blending could not guarantee consistent proportions
- Existing packing was manual, limiting output
- The trader needed to serve several markets with different formulas
Limits we designed around
Real projects are never ideal. These constraints shaped the configuration and delivery plan.
- Very short project window (under 3 months to production)
- Low capital budget - no dryer, boiler or complex process
- Simple maintenance by a small local team
- Multiple bag sizes for different markets
Why we configured it this way
A standard four-hopper BB line with automatic proportioning was the right fit: low investment, fast fabrication, and immediate formula flexibility. A gentle rotary mixer preserved granule quality, and semi-automatic bagging with a checkweigher improved consistency without over-automating. The line was designed for quick changeover so the trader could switch formulas between markets in minutes.
How it was delivered
From requirements confirmation to commissioning - the key nodes of this project.
Formula & capacity review
Confirmed 4 initial formulas, particle sizes and 5 t/h target.
Standard line build
Hopper scales, rotary mixer, conveying and bagging fabricated from stock designs.
Shipping & installation
Expedited export packing and supervised installation.
Training & launch
Trained local operators on formula memory and changeover; launched before the season.
Difficult points and how we solved them
3-month deadline
Stock-standard configuration with no custom parts kept fabrication and delivery on schedule.
Granule breakage
Rotary mixer with gentle tumbling action selected over aggressive paddle mixing.
Multiple formulas
PLC recipe memory for 4+ formulas with a cleaning procedure between blends.
What changed after delivery
Verifiable changes from this project. Where specific figures are confidential, we state the direction and the evidence.
- Order to operation in under 3 months
- Customer launched regional NPK blends with 4 formulas in the first season
- Lower working capital tied up in finished inventory
- The standard configuration became the template for a second line
Project outcome
Клиент запустил региональные NPK-смеси с 4 рецептурами в первый сезон.
What similar customers can learn
For traders and distributors, this case shows that a BB line is a low-risk entry into fertilizer production: fast to market, formula-flexible and simple to maintain. The same line can scale with additional hoppers and automatic packing as volume grows.
