The Grapple is a robust, typically hydraulically actuated grabbing device integrated into or adjacent to the pulper tank. The Grapple’s primary function is to scoop, capture, and remove floating and near-surface light impurities from the pulp stock as it circulates within the pulper. The design often includes multiple articulated fingers or tines, adjustable gripping force, and a sealable cage or basket to retain collected impurities for disposal or recycling.

 

Benefits and Performance Metrics of Grapple

1. Cleaner pulp entering the refiner: Reduces wear, caking, and pitch buildup downstream.
2. Reduced screen and grate fouling: Prolongs screen life and maintains throughput.
3. Improved formation and drainage: Fewer floating impurities translate to more uniform sheet formation.
4. Less downtime: Automated impurity removal minimizes manual intervention during shifts.
5. Improved material recovery: Trapped plastics and foams can be diverted to recycling streams rather than ending up in waste.

 

In modern paper production, the pulper is a critical stage where shredded stock is separated from contaminants and prepared for refining and forming. Therefore, the existence of a Grapple is crucial and essential. Welcome to contact us for more details.
