Waste carton—whether household packaging boxes or industrial corrugated cardboard boxes—are one of the world’s most abundant and valuable sources of secondary fiber. Waste carton recycling and pulping equipment is a professional industrial system that can transform these waste carton into high-quality pulp, which can then be used to produce a variety of paper products such as kraft paper, linerboard, and corrugated paper.
| Step | Equipment / Stage | Description |
|---|---|---|
| 1 | Conveying | Steadily feed waste cartons into the pulping system via chain conveyor |
| 2 | Pulping / Disintegration | Disintegrate cartons into fiber slurry in a hydrapulper (e.g., D‑Type Hydrapulper) |
| 3 | Discharge & Storage | Discharge slurry into a dump chest for temporary storage |
| 4 | High Density Cleaning | High‑density cleaners remove heavy contaminants (sand, glass, metal) |
| 5 | Coarse Screening | Primary coarse screens remove unfibrated large particles |
| 6 | Low Density Cleaning | Multi‑stage low‑density cleaners remove fine contaminants |
| 7 | Fine Screening | Fine screens remove remaining small impurities |
| 8 | Refining | Double‑disc refiners fibrillate fibers to enhance bonding strength |
| 9 | Pulp Storage | Refined pulp is stored in the storage chest for papermaking |
| 10 | Papermaking | Pulp is formed into paper on the paper machine (wire, press, dryer sections) |
The waste carton recycling and pulping equipment, from crushing, pulping, impurity removal, screening to refining and papermaking, efficiently transforms waste carton into high-value-added recycled packaging paper. It not only solves the problem of solid waste treatment, but also provides a sustainable fiber source for the paper industry. Our email: leizhanpulper@gmail.com
