Manufacturing Process – Engineering Workflow
Step 1 – Raw Material Preparation & Grinding
Feedstock ground to 2.0–3.0mm for feed or 4.0–6.0mm for biomass. Magnetic separator removes ferrous contaminants. Moisture adjusted to 14%–16%.
Step 2 – Conditioning & Steam Treatment
Double-shaft paddle conditioner with steam injection at 0.2–0.4 MPa. Retention time 45–60 seconds. Mash temperature elevated to 80–95°C.
Step 3 – Pelletising (Core Forming Process)
Main motor drives ring die rotation at 4–8 m/s peripheral speed. Roller gap maintained at 0.15–0.30 mm. Process monitored via PLC with real-time adjustments.
Step 4 – Counterflow Cooling
Ambient air drawn counter-current through pellet bed. Retention time 6–10 minutes. Pellet exit temperature ≤ ambient +5°C. Final moisture ≤12%.
Step 5 – Screening & Bagging
Vibrating screener removes fines. Automatic bagging scale with ±0.2% tolerance.

Engineering Case Study – Support After Installation in Nigeria
Project Background
A poultry feed mill in Ogun State purchased a 90kW pellet mill (2.5 t/h). Installation completed with factory supervision. After 6 months, production output dropped from 2.5 t/h to 1.8 t/h.
Initial Problem
Output drop with no apparent cause. Local operators unable to diagnose. Downtime cost estimated at $500 per hour.
Root Cause Analysis
Roller gap had opened from 0.20mm to 0.45mm due to normal wear and lack of adjustment. Die holes partially blocked with fines.
Solution Implemented
Remote technical support call with video. Adjusted roller gap to 0.20mm. Cleaned die holes with brush. Operator retraining on weekly gap checking.
Final Data Results
| Metric | Before Support | After Support |
|---|---|---|
| Throughput | 1.8 t/h | 2.4 t/h |
| Roller gap | 0.45mm | 0.20mm |
| Downtime (diagnosis) | 8 hours | 1 hour |
| Operator retraining | 0 hours | 2 hours |
| Production restored | 2 days | Same day |
