Parason Fractionator separates the fibers mainly by fiber length and is fitted with a hole or slot type baskets. The specially designed rotor with fabricated and contoured foils generates lower positive pulses and higher negative pulses. Hence requires low energy consumption and a higher purging effect to keep the basket clean.
The purpose of fractionation is to separate long fibers and short fibers according to various characteristics, such as fiber length, type of fiber, etc. Depending on requirements, each fractioned pulp is then used directly for papermaking or undergoes further treatment.
