A corrugated strippings shredder is a machine designed to shred the edge trim or leftover cuttings (strippings) from corrugated cardboard sheets—typically waste generated during the die-cutting or slitting process in packaging or box manufacturing facilities.
✅ Common Applications:
- Box making plants
- Corrugated cardboard production
- Packaging factories
- Facilities using die-cutting machines
✅ Example Integration:
It’s often placed inline after die cutters, feeding the shredded strippings directly into:
- A baler (for compacting)
- A conveyor (for waste transport)
- A dust extraction system (for air filtration)
🔄 Typical Types of Industrial Shredders for Corrugated Strippings
For shredding corrugated strippings (the thin, long, and often curly edge waste from corrugated cardboard), industrial shredders need to be efficient, jam-resistant, and suited for high-speed production environments. Here are the typical types of shredders used for this specific task:
⚙️ 1. Single Shaft Shredders
- Best for: Bulkier or thicker edge trim or offcuts, not too stringy.
- Mechanism: A rotor with blades shears material against a fixed counter-blade.
- Advantage: Versatile and can handle mixed paper waste as well.
- Limitation: Not ideal for long, stringy trimmings without pre-cutting or fluffing.
⚙️ 2. Double Shaft (Dual Shaft) Shredders
- Best for: Heavy-duty shredding of tangled or bulky corrugated waste.
- Mechanism: Two counter-rotating shafts with blades pull and tear the material.
- Advantage: High torque; can deal with tough or wadded-up strippings.
- Limitation: Slower throughput and less fine particle size.
⚙️ 3. Granulators
- Function: Used after shredders to reduce pre-shredded cardboard into small, uniform particles.
- Blades: Typically use open or staggered rotor designs for soft materials like corrugated board.
- Output: Fine flakes ideal for recycling, composting, or use as packing filler.
- Setup: Often used in 2-stage systems (shredder + granulator).
Summary Table:
| Type | Ideal For | Advantages | Limitations |
|---|---|---|---|
| Single Shaft Shredders | Thicker or mixed corrugated offcuts | Versatile, good for bulk, consistent size | Can jam on long stringy trim without pre-cutting |
| Double Shaft Shredders | Heavy-duty or tangled strippings | High torque, handles tough or wadded waste | Slower speed, uneven size output |
| Granulators | Post-shredding fine granulation | Uniform small particle size, recyclable-ready | Requires pre-shredding or feeding control |
