Fractionation Screen

The Fractionation Screen is a specialized machine for pulp fiber classification, separating fibers into long, medium, and short categories based on their specific characteristics. This process enhances paper production by tailoring fiber types for different layers of cardboard or paper products, improving strength, cleanliness, and performance.

Using the fractionation screen, long fibers contribute to the base layer for superior strength, medium fibers enhance the surface quality and bursting strength, and short fibers serve as fillers to increase paper weight and utilization efficiency. This advanced screening system ensures that raw pulp is effectively processed for a wide range of paper-making applications.

• Precise Fiber Separation: Efficiently classifies fibers into long (150-220 μm), medium (120-150 μm), and short (less than 120 μm) fractions for optimized paper production.

• Improved Paper Strength: Long fibers enhance the bottom layer, significantly increasing the finished paper's structural integrity.

• Enhanced Surface Cleanliness: Medium fibers, after additional treatments like hot dispersion or impurity removal, improve the paper's cleanliness, dyeability, and bursting strength.

• Cost-Effective Utilization: Short fibers serve as economical fillers, maximizing material usage and reducing waste in recycled paper production.

• Versatile Applications: Suitable for producing multi-layer cardboard, kraft paper, and other paper products requiring tailored fiber distribution.

• Optimized Pulp Processing: Streamlines the pulp fractionation process, improving the efficiency and output quality of the papermaking operation.
