The reject separator, as the name suggests, primarily functions to “separate” and “discharge sludge.” It is strategically positioned at multiple critical nodes in the pulping process, such as after pulping, before screening, and after thickening. Utilizing physical principles, it removes impurities that differ in density or shape from the qualified fibers.

The importance of the reject separator is reflected in three aspects:
Protective Equipment: Effectively removes hard impurities (such as metal and stones) to prevent wear and damage to subsequent precision equipment like pumps, screening drums, and pulpers, thereby extending the service life of the equipment.
Quality Enhancement: Removing light impurities (such as plastic fragments) and heavy impurities to ensure the cleanliness of the pulp is crucial for producing high-grade paper.
Stable Production: Prevent pipeline and screen drum blockages, reduce unplanned downtime, and ensure continuous, stable, and efficient operation of the production line.

Therefore, the waste pulp reject separator is an indispensable key piece of equipment in modern pulping plants. If you would like to learn more details about the pulping machine, please send us an email for consultation. Our email address: wastepapermachine@gmail.com
