Thin Stock Screening

Visit goo.gl/zoc5gV to view the full video and purchase access to our other Paper courses.
The purpose of thin stock screening is to remove debris from the dilute stock going to the headbox. Screening also deflocculates the stock and protects downstream equipment. Screening systems often use two or three "cascaded" stages in order to reduce fiber losses and improve overall debris removal efficiency. The design and operation of a screening system must take into account the requirements of the paper or board machine, desired sheet quality and properties, and characteristics of the particles to be removed.
