What Is a Refiner Disc? A refiner disc (also known as a refiner plate) is one of the most critical components in the pulp refining process. Installed inside disc refiners, it is responsible for treating fibers before they enter the papermaking stage. During operation, pulp passes between two discs—either one rotating and one stationary, or…
Paper Recycling for Paper Mill: Process, Equipment, and Practical Optimization Guide Meta Description A practical guide to paper recycling for paper mills. Learn how the recycling process works, what equipment is used, and how to improve pulp quality and production efficiency. Introduction In today’s paper industry, recycling is no longer just an environmental choice—it’s a…
Screening is one of the most critical processes in modern pulp and paper production. Whether processing virgin pulp, recycled fiber, or mechanical pulp, screening systems are responsible for removing contaminants, improving pulp quality, and protecting downstream equipment. Among the most commonly used screening equipment in stock preparation systems are inflow pressure screens and outflow pressure…
In industrial production, filtration is a critical step for ensuring product quality and protecting downstream equipment. In the pulp and paper industry, screening baskets (also known as screen cylinders or screen drums) are widely used to remove impurities from pulp slurry. But a common question arises in other industries such as printing ink manufacturing, coatings,…
In the modern paper and pulp industry, equipment that can consistently deliver high-quality fiber processing while minimizing energy consumption and operational costs is paramount. Among such innovations, the Low Consistency Refiner, often referred to as a Double disc refiner, Fiber Deflaker, or High-Frequency Deflaker, has gained wide adoption. This machine plays a crucial role in…
The high-frequency fiber deflaker is mainly used to gently loosen and disperse fibers, improving the uniformity and dispersion of the pulp and enhancing its beatability. During subsequent stock approach and sheet forming on the paper machine, this helps effectively prevent cloudiness and coarse spots on the paper surface, reduce surface defects of the finished paper,…
