Reference Delivery
Integrated feed mill — Ghana
Illustrative scenario: turnkey 20 t/h pelleted feed mill supplying an integrator's broiler and layer flocks across southern Ghana. Sourcing covered raw-material intake, hammer mill, mixer, pellet press, cooler, bagging and bulk out-loading, with soybean and maize handled locally alongside imported additives.

Load requirements
Design loads used to size housing, utilities and equipment.
Line capacity
20 t/h pellet, 6 t/h mash bypass
Silo storage
8 × 500 t raw + 6 × 200 t finished
Peak electrical load
1.35 MW installed, 900 kW running
Steam demand
1.8 t/h saturated at 6 bar
Batch cycle
6 min mixer cycle, 4 batches queued
Bulk out-loading
40 t truck load in ≤25 min
System design choices
Why each subsystem was specified the way it was.
| Area | Choice | Rationale |
|---|---|---|
| Grinding | 1,200 mm hammer mill + hopper aspiration | Handles 25 t/h maize at 3 mm screen with steady amp draw and low dust carry-over. |
| Mixing | 2 t twin-shaft paddle mixer + liquid dosing | Achieves CV <5% in ≤75 s and dosing accuracy ±0.3% for fats and enzymes. |
| Pelleting | 250 kW ring-die + double conditioner | Double conditioner raises meal temp to 82 °C, improves PDI ~4 pts vs single conditioner. |
| Cooling | Counter-flow cooler + rotary sifter | Pellet temp within 5 °C of ambient at exit; fines returned to conditioner for re-pelleting. |
| Traceability | PLC-linked batch records + lot codes at bagging | Required by Ghana FDA feed-safety inspection and integrator's HACCP program. |
Results
Representative KPIs achieved on projects of this scope.
Pellet durability (PDI)
93.2%
Fines at bagging
3.1% by weight
