| Parameter | Specification Range / Limit | Purpose / Impact |
|---|---|---|
| Wood Species | Acacia, Eucalyptus (hardwood) or specific softwoods | Dictates fiber length, tear resistance, and final paper brightness/strength. |
| Moisture Content | 45% – 55% (green/fresh) or 10% – 25% (air-dried depending on trade) | Affects chip handling, bulk density, and chemical dilution during digestion. |
| Thickness | 3 mm – 8 mm (Max 6–10 mm) | Crucial for liquor penetration; over-thick chips cause uncooked centers (rejects). |
| Acceptable Length/Size | 9.5 mm – 28.6 mm (approx. 85%–90% min) | Ensures uniform packing density and predictable flow in continuous digesters. |
| Fines (< 3-5 mm) | < 2% – 5% max | Prevents over-consumption of cooking chemicals and drainage issues. |
| Oversize (> 30-45 mm) | < 5% – 10% max | Requires re-chipping to prevent cooking bottlenecks. |
| Bark and Rot Content | < 1% – 1.5% max | Minimizes pulp contamination, dark specks, and bleaching chemical costs. |
