Shredded Paper & Cardboard
Cellulose (C₆H₁₀O₅)n · Shredded Paper · Shredded Cardboard · Paper Fiber · Recovered Fiber · OCC Shred
Shredded paper and cardboard are recycled fiber materials produced through shredding, grinding, or processing of paper-based products. The material is lightweight, fibrous, and highly compressible, making it difficult to handle with conventional bulk material equipment. Shredded fibers tend to interlock, bridge, and compact, creating challenges for consistent material flow. In addition, dry paper fibers can generate combustible dust requiring proper containment and housekeeping. KWS designs specialized conveying systems that ensure reliable handling while minimizing plugging, dust generation, and maintenance requirements.

Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Shredded Paper, Shredded Cardboard, Fiber Fluff, Recycled Fiber Feedstock |
| Bulk Density | 4-15 lb/ft³ (depends on shred size, compaction, and moisture content) |
| Flow Behavior | Poorly flowing; fibrous particles tend to bridge, mat, and interlock |
| Abrasiveness | Low Soft cellulosic material |
| Corrosiveness | Not Corrosive |
| Dust Potential | High Fine paper dust is combustible and requires containment |
Handling Challenges
- Bridging and ratholing in hoppers and storage bins
- Compaction and plugging in conveying equipment
- Combustible dust hazards requiring explosion protection measures
- Variable feed rates caused by low bulk density and compressibility
- Material buildup and housekeeping requirements
Summary
Shredded paper and cardboard require conveying and storage systems designed for lightweight, fibrous, and combustible materials. KWS Manufacturing provides engineered solutions—including shaftless screw conveyors, drag conveyors, and live bottom bins—that ensure reliable material flow while minimizing plugging and maintenance.
With extensive experience handling recycled fibers, biomass materials, and difficult-to-flow bulk solids, KWS ensures efficient, dependable, and low-maintenance operation for shredded paper and cardboard handling systems.
