The Reject Separator is a specialized pulping machine applied in the stock preparation system to separate usable fiber from unwanted materials. During the pulping and screening process, various contaminants—such as plastics, wires, tapes, stickies, sand, and other coarse impurities—are removed from the pulp. However, these rejects may still contain a significant amount of recoverable fiber. For paper mills, the Reject Separator is not simply a reject-handling device. It is an important part of a complete and efficient stock preparation system.

 

The reject material enters the Reject Separator through the inlet and is evenly distributed inside the separation chamber. Under the combined action of mechanical agitation, dilution, and controlled flow, the remaining fibers are detached from the contaminants. The recoverable fibers pass through the separation openings and are collected for further processing or returned to the pulp line. Larger and heavier impurities, as well as other coarse rejects, are retained and discharged separately. The Reject Separator can be integrated into different stock preparation systems and adapted to various pulp materials and production requirements. Its stable operating performance helps paper mills maintain consistent process conditions.
