Reject Separator for Paper Mill Stock Preparation

Leizhan’s solution leverages advanced separation physics to achieve superior performance. The design of Reject Separator typically centers on a pressure screen or gravity-fed vortex separator principle, optimized for the harsh, abrasive nature of reject streams. To handle the concentrated contaminants, the Reject Separator employs a reliable reject discharge valve. Advanced models may include automatic, intermittent backflushing systems that use clean water or filtrate to dislodge any particles clogging the screen, ensuring continuous, stable operation without manual intervention.
Advantages for the Paper Mill
1. By recovering up to 90-95% of the fibers from the reject stream, the Reject Separator directly reduces the mill’s demand for virgin pulp or purchased pulp. This has a significant positive impact on raw material costs.
2. By continuously and efficiently removing contaminants from the process loop, the Reject Separator protects downstream equipment—such as fine screens, cleaners, and the paper machine itself—from wear, damage, and sheet defects (like holes or spots).
3. Clean filtrate from the Reject Separator is typically recirculated within the process, reducing fresh water consumption and the load on the mill’s effluent treatment plant.
For any paper mill looking to modernize its stock preparation plant, it represents a critical component for achieving a cleaner, more efficient, and more sustainable production cycle.
