In the pulping process, the core working principle of the reject separator is the ingenious combination of centrifugal force and fluid dynamics, making it a key piece of equipment for ensuring the final pulp product quality, reducing production costs, and achieving clean production.

In a typical pulping process, the reject separator typically appears in the following positions:
After pulping (rough selection stage): As a primary purification device, it removes large heavy impurities brought from waste paper or logs.
Pre-screening (Protective Section): Installed before the pressure screen to ensure the pulp entering the precision screen is clean and to protect the expensive screen drum.
Post-screening (Tailings Treatment Section): Process the tailings discharged from the pressure screen, concentrate them, recover the good fibers, and discharge the high-concentration impurities from the system.
