The thin stock system is responsible for supplying clean, dilute stock to the headbox of a paper or board machine. The thin stock system uses white water to dilute the stock to the proper consistency for cleaning, screening, and delivery to the headbox. This module will list the objectives of a thin stock system and identify how each objective is satisfied.
