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.
