Waste Paper Bale Breaker For Paper Mill

The SBJ Series Bale Breaker is a robust, drum‑type machine specifically designed to break and sort waste paper bales before they enter the pulping line. Operating under dry conditions, this equipment efficiently separates loose paper from small impurities such as sand, staples, plastic fragments, and glass pieces. By integrating a bale breaker into your system, you significantly reduce wear on downstream machinery – from pulpers and cleaners to pipes, pressure screens, and refiners.

Key Features of the SBJ Bale Breaker

Dual‑purpose action – Breaks compressed waste paper bales and performs dry selection in a single pass.

Perforated drum design – The rotating drum features holes that allow small contaminants to fall out, leaving cleaner paper fibers for further processing.

Protects critical equipment – Removing impurities early extends the service life of pulpers, pumps, pressure screens, and refiners, lowering overall maintenance costs.

High throughput capacity – Handles from 220 to 1500 tonnes per day, depending on model.

Installing a dedicated bale breaker before the pulper reduces the risk of damage from hard contaminants. It also lowers energy consumption downstream, because the pulper receives cleaner, already‑broken material. The dry‑selection process requires no water, saving resources and simplifying impurity disposal. Every SBJ bale breaker is built for continuous, heavy‑duty operation in waste paper recycling plants.
