Laboratory Mini Desktop Shredder
Rumtoo’s compact shredder lets labs, makers, and R&D teams recycle small batches of plastics, rubber, and light metals directly on the bench—turning scrap into consistent feedstock without industrial-scale equipment.
- Desktop-sized footprint
- Dual H13 blade stacks
- Runs on 220 V household power
Small Footprint, Real Shredding Power
Purpose-built for laboratories and pilot lines, the mini desktop shredder combines dual H13 blade assemblies with a 1.5 kW geared motor. Feed plastics, films, rubber, or thin sheet metal through the 120 mm × 200 mm port and recover uniform flakes for testing, compounding, or filament extrusion.
- Handles small batches without tying up full-sized shredders.
- Quiet, enclosed design fits onto a lab bench or rolling cart.
- Forward/reverse controls simplify clearing jams during experiments.

Short demo showing how lab-scale scrap turns into uniform flakes ready for compounding or filament extrusion.
Quiet operation and quick forward/reverse controls keep experiments running smoothly.
Key Benefits
Engineers and researchers gain on-demand shredding without outsourcing or waiting for large-batch equipment.
Bench-Ready Dimensions
Weighing just over 100 kg, the shredder fits on a lab bench or tool cart yet delivers continuous-duty torque.
Precision Blade Sets
Swap between 5 mm or 3 mm blade stacks to tune flake size for downstream melt tests or compounding trials.
Low Energy, High Value
Runs on standard 220 V power, letting labs recycle failed prints or molding scraps without extra infrastructure.
How the Mini Shredder Works
A three-step process turns bench-scale scrap into ready-to-reuse flakes.
Drop sprues, failed prints, films, or thin sheet metals through the guarded 120 × 200 mm feed port.
The geared 1.5 kW motor drives counter-rotating H13 blades that shear material into uniform strips or flakes.
Shredded output drops into a tray or bag for immediate reuse in compounding, filament extrusion, or melt-flow testing.

| Blade material | H13 tool steel, 100 mm diameter |
| Motor & gearbox | 1.5 kW geared drive, forward / reverse / stop controls |
| Power supply | 220 V single-phase household electricity |
| Machine weight | ≈ 101 kg |
Need different flake sizes, safety interlocks, or voltage? Rumtoo engineers can tailor the design for your lab protocols.
Typical Applications
Tailored for R&D, universities, and light-production lines that need rapid recycling loops.
Materials Research Labs
Prepare consistent flake feedstock for rheology, compounding, or additive manufacturing experiments.
Product Development
Recycle prototype parts and failed 3D prints on-site to cut material costs and lead times.
Educational Makerspaces
Teach circular economy principles by turning classroom scrap into reusable pellets or filament.
Operation & Maintenance Tips
Use these quick checklists to keep the desktop shredder safe and productive.
Before Each Session
- Verify the feed port is clear and guards are in place.
- Check the direction of rotation after power-up.
- Inspect blades visually for wear or foreign objects.
During Shredding
- Feed small batches; avoid exceeding the port height.
- Use the reverse function to clear occasional jams.
- Route shredded output into a bin or liner for tidy collection.
Routine Care
- Lubricate bearings and gearbox per the manual.
- Rotate or replace blades when flake size becomes inconsistent.
- Disconnect power before servicing or cleaning the chamber.
Why Choose Rumtoo’s Desktop Shredder
Compared with improvised grinders or outsourcing small runs, the mini shredder delivers faster iterations.
| Aspect | Rumtoo Mini Desktop Shredder | DIY / Outsourced Solutions |
|---|---|---|
| Footprint | Bench-friendly, plug-and-play on 220 V. | Large industrial machine or off-site processing. |
| Flake consistency | Dual blade sets tailored to lab requirements. | Inconsistent particle size from improvised tools. |
| Turnaround time | Immediate recycling during R&D iterations. | Wait for scheduling or shipping to service providers. |
| Safety & noise | Guarded port, forward/reverse controls, quiet enclosure. | Open blades or noisy shop equipment. |
| Total cost | Low operating costs, eliminates outsourcing fees. | Recurring service costs and higher scrap rates. |
What Users Say
Labs and makerspaces use the Rumtoo mini shredder to accelerate prototypes and recycling education.
“We recycle failed prints within minutes now, so our filament R&D cycles aren’t waiting on external services.”

Frequently Asked Questions
What materials can the mini shredder handle?
It is designed for plastics (PLA, ABS, PETG, PP, PE), flexible films, rubber samples, and thin sheet metals that fit the feed port. Share your material list with Rumtoo if you require confirmation.
Can we change blade sizes?
Yes. Two blade sets are available (5 mm and 3 mm). Swapping requires minimal downtime, letting you tune particle size for different experiments.
How loud is the shredder?
Noise levels stay within typical lab equipment ranges thanks to the enclosed housing and small motor. Hearing protection is generally not required, but follow your facility guidelines.
Does it need industrial power?
No. The standard unit plugs into a 220 V single-phase outlet, making it ideal for labs, classrooms, and small workshops.
What’s the maintenance schedule?
Routine blade inspection, lubrication, and cleaning are usually sufficient. Rumtoo provides a maintenance checklist and spare parts kit.
