As a key piece of equipment in modern pulp and paper industry, the reject separator plays a crucial role in enhancing production efficiency and improving pulp quality. During the papermaking process, raw materials such as wood and waste paper undergo complex treatments to convert into high-quality pulp, inevitably generating impurities. If these impurities are not promptly removed, they can not only affect pulp quality but also compromise subsequent paper making processes. Thus, the reject separator emerges to efficiently eliminate various impurities from the pulp, including plastics, metal fragments, and fiber clusters, through advanced separation technologies.

The working principle of the reject separator primarily relies on physical separation technology. It typically consists of a high-speed rotating screen or centrifugal device, which separates heavy impurities from light pulp through centrifugal force or liquid pressure. The machine’s design takes into account the flow velocity and direction of water, allowing impurities to be automatically discharged into a collection tank while the pulp flows through the screen. To achieve more efficient separation, modern reject separators are often equipped with an automatic control system that adjusts operational parameters in real time based on pulp concentration and flow rate. This not only enhances separation efficiency but also reduces equipment energy consumption.
