De-barking and Chipping

Bark is stripped from the logs by knife, drum, abrasion, or hydraulic barker. The stripped bark is then used for fuel or as soil enrichment.

Stripped logs are chipped into small pieces by knives mounted in massive steel wheels (used in chemical pulping process).

The chips pass through vibrating screens, whereby both undersized chips, dust etc and oversized chips are rejected.

Accepted chips are then stored in huge bins ready for the next process.
