In a waste paper pulping line, the single fiber separator must not only further defiberize residual paper fragments from the initial pulping stage into individual fibers but also separate light and heavy impurities within the same unit by leveraging differences in specific gravity. This multifunctional role—combining defiberization, impurity removal, and coarse screening—positions the single fiber separator as a critical link connecting the pulping and fine screening stages of the process..
The impeller features a specialized shape and rotates at high speed on the main shaft, simultaneously defibering the pulp and separating light and heavy impurities. Its rotation generates intense shear forces and a centrifugal force field: the shear forces break down residual paper fragments into fibers, while the centrifugal force stratifies materials based on their specific gravity.
The screen plate is fitted with a bottom blade to prevent fibers from wrapping around the impeller, the screen plate utilizes a stepped-hole design that facilitates pulp flow and impurity retention while minimizing clogging.
The reject discharge system enabling automatic, periodic discharge of heavy impurities. This design prevents the fragmentation and breakdown of impurities, reduces the load on downstream screening equipment, and ensures continuous, stable operation.
