Industrial Process

The process of pulp production begins with the handling of the raw material which occurs in the wood yard, where the logs are received from the forest with the bark removed. The logs are taken to a storage yard or directly to the chipper according to a pre-determined sequence.

The logs are unloaded onto feeding tables, washed, and carried by conveyors to the chipper. A 12-blade rotating disc transforms the logs in a few seconds into small chips, which are deposited on a chip yard.

Chipping is carried out with a view toward the ideal chip size for the cooking stage. Separation of the chips by size occurs on a vibrating sifter before they enter the contnuous digester’s chip silo. Chips not meeting specifications are removed, to be utilized as fuel for the biomass vessel.

Chips within specifications are transported to the continuous digester’s chip silo on conveyors with metal detection systems to avoid damage.
