Against the backdrop of growing global agricultural demand, establishing an efficient and environmentally friendly fertilizer production line has become a strategic choice for many enterprises. This article systematically introduces 6 key steps in planning a fertilizer production line to help you avoid common pitfalls and build competitive production facilities.
Industry Data: According to IFA statistics, global fertilizer production reached 250 million tons in 2022, with compound fertilizers accounting for about 45%, while organic fertilizers showed the fastest growth at 8% annually.
1. Define Production Requirements: Start with Product Positioning
Before planning the production line, three core questions must be answered:
- What to produce?– Organic, compound, water-soluble or specialty fertilizers? Different products require vastly different processes
- How much to produce?– 50,000 or 100,000 tons annual capacity? Output determines equipment scale
- What to produce with?– Raw material characteristics (moisture, particle size, corrosiveness) directly affect equipment selection
| Fertilizer Type | Core Process | Key Equipment |
| Organic Fertilizer | Fermentation+Crushing+Granulation | Fermentation Tank, Crusher, Disc Granulator |
| Compound Fertilizer | Batching+Mixing+Granulation | Batching System, Mixer, Rotary Drum Granulator |
| Water-soluble Fertilizer | Dissolution+Mixing+Packaging | Reactor, Mixing Tank, Liquid Packing Machine |
2. Process Selection: Match Product with Market
Different process routes have their pros and cons, requiring comprehensive consideration of product quality, energy consumption and investment costs:
| Process Type | Suitable Products | Investment Cost | Energy Consumption |
| Pelletizing Granulation | Standard Compound Fertilizer | Low | Medium |
| Extrusion Granulation | High-concentration Compound Fertilizer | Medium | Low |
| Melting Granulation | Premium Specialty Fertilizer | High | High |
3. Equipment Selection: Building Production Core
Typical equipment configuration for a 50,000 tons/year compound fertilizer production line:
[Raw Material Pretreatment] → [Batching & Mixing] → [Granulation] → [Drying & Cooling] → [Screening & Coating] → [Packaging & Storage]- Crusher:Capacity 2-3 tons/hour, output particle size ≤2mm
- Mixer:Batch capacity 1 ton, mixing uniformity ≥95%
- Granulator:Rotary drum type, diameter 2.5m, capacity 2.5 tons/hour
- Dryer:Gas-fired hot air furnace, temperature range 80-200℃
4. Plant Layout: Optimizing Production Flow
Efficient layout should follow these principles:
- Linear arrangement according to production sequence to minimize material transfer
- Maintenance space reservation (aisle width ≥1.5m)
- Explosion-proof measures in dust-prone areas
- Centralized control room for key parameters monitoring
5. Investment Budget: Cost and Risk Control
| Item | Investment Range (10K USD) | Notes |
| Core Equipment | 120-220 | Granulator, Dryer, Batching System |
| Auxiliary Equipment | 45-75 | Conveying, Environmental, Control Systems |
| Plant Construction | 75-150 | Standard 10,000 sq.ft facility |
| Total Investment | 270-490 | Varies with automation level |
6. Implementation Path: From Planning to Operation
- Obtain necessary permits (environmental approval, production license)
- Equipment procurement and installation (prefer suppliers with industry experience)
- System commissioning and trial operation (72-hour continuous test)
- Staff training and operating procedures development
- Official production launch and continuous optimization
