Production line and factory setup overview
A small/medium bulk-blending line producing declared NPK grades from purchased compatible dry granular fertilisers through supplier-certificate release, segregated humidity-controlled storage, screened feeding, gravimetric recipe batching, gentle low-segregation blending, surge transfer, automatic weighing into 25-50 kg bags, stitching, coding, check weighing, nutrient verification and retained-sample control. It performs physical blending only—not ammonia chemistry, acid processing or compound-fertiliser granulation.
Recommended lowest-entry line configuration Launch one agronomist-approved grade at 2-5 t/h using compatible, closely matched granule sizes of certified urea, DAP or MAP and potash. Include three to four covered bins, independent weigh hoppers, a gentle batch or rotary blender, short-drop conveyors, surge hopper, 25-50 kg net weigher, stitcher, coder, check scale and nutrient sampling. Keep incompatible or hygroscopic materials out until storage and caking trials are passed.
Production process and implementation sequence
- Ingredient certificate and compatibility release
- Dry segregated storage and screened feeding
- Independent gravimetric batching
- Gentle low-segregation blending
- Short-drop surge transfer
- Net weighing, stitching and coding
- Check weighing and nutrient sampling
- Retained sample and lot release
Products, capacity and market fit
- Afghan dealers can supply crop- and region-specific blends from standard imported nutrients.
- Physical blending needs far less capital than chemical fertiliser manufacture.
- One grade controls inventory, formulation and segregation risk.
- Certified inputs, accurate weighing and nutrient assays protect farmers and the brand.
- Bulk-blended granular NPK fertiliser - Declared N-P2O5-K2O grade, ingredient sources, granule range, moisture, segregation, net mass and legal label - Crop-specific Afghan farm supply under agronomic recommendation
Core production machinery and line specifications
| Machine / stage | Function / value | Production note |
|---|---|---|
| Three to four segregated feed bins | Keeps certified ingredients dry and separate | Matched granule sizes |
| Independent weigh hoppers | Meters each NPK recipe component | Calibrated gravimetric |
| Gentle batch or rotary blender | Mixes without crushing granules | 2-5 t/h |
| Low-drop conveyors and surge hopper | Limits post-blend segregation | Short transfer path |
| Net weigher, stitcher and coder | Packs declared grade | 25-50 kg |
| Sampling and nutrient-control station | Verifies formula and uniformity | Retained lot sample |
