Stock preparation Introduction Stock preparation is a crucial stage in the paper manufacturing process. It involves the initial treatment and processing of raw materials, such as wood pulp, recycled paper, or other fibers, to create a homogeneous pulp mixture that can be used to produce paper. The goal of stock preparation is to convert the raw materials into a consistent and quality pulp suitable for the papermaking process. This stage involves several key steps, including: Fiber Treatment: The raw materials, such as wood chips or recycled paper, undergo various treatments to remove impurities, such as bark, dirt, and ink. This step may include processes like screening, shredding, and cleaning. Pulping: Pulping is the process of breaking down the raw materials into individual fibers
