The Bale Breaker is a mechanical device used to loosen and separate tightly compressed bales of waste paper (such as ONP—Old Newsprint, OCC—Old Corrugated Containers, or mixed paper) into manageable flakes or bundles. TheseBale Breakers, often weighing 500–1,200 kg and bound with steel or plastic strapping, must be “opened” before they can be effectively fed into a pulper. Without proper bale opening, mills risk uneven feeding, pulper overloads, and reduced repulping efficiency.

 

Design Features of Bale Breaker

 

1. Built from welded structural steel with reinforced mounting points to absorb high impact loads during bale processing.
2. The spacing between drums and rotational speed can be adjusted based on bale type (e.g., soft mixed paper vs. dense OCC), optimizing fiber opening while minimizing damage.
3. Enclosed housing with access doors and optional dust extraction ports helps control airborne particles and maintain a cleaner working environment.

For paper mills looking to optimize their stock preparation line—especially when scaling up use of recovered paper—investing in a well-designed bale breaker like Leizhan’s is a strategic step toward smoother, safer, and more efficient production.
