Chip washing

Producing quality pulp requires chips that are as free from impurities as possible, not only for pulp quality but also with respect to wear on the equipment.

The growing use of purchased chips, from sawmills, results in an ever-increasing need for chip washing. Existing impurities, in the form of metal, stones and sand, must be removed before the chips enter the process.

Chip washing saves wear on production machinery, such as feed screws and refiner segments – a major maintenance expense.
