Abstract
With increasing use of recycled fiber in papermaking, the hydroclone has become a staple piece of equipment in every paper mill. Hydroclones, or centrifugal cleaners, use a combination of centrifugal force, hydraulic shear, and hydraulic drag to separate fibers from heavy debris based on their density differences with water. The shape of the debris also affects removal. Hydroclones can be used to fractionate fiber. The cleaner underflow, or reject stream, contains the less refined, longer, stiffer, and lower specific surface area fibers, and high-density debris. The overflow, or accept stream, contains more of the extreme fines, well-refined and flexible fibers, and low-density debris.
