Robust Lab SD450 Shredder

Robust
A compact, single-rotor shredder that handles wood offcuts, plastics, cardboard, and mixed packaging waste in one machine — practical for workshops where floor space is tight and waste streams are varied.

Typically chosen by

  • Joinery and timber workshops needing to reduce offcuts and wood waste to a manageable, consistent particle size
  • Operations handling a mix of materials — wood, plastics, cardboard, and packaging — from a single machine rather than several
  • Facilities where floor space is limited but throughput demands are moderate, and where tidy, contained output matters

Key specification considerations

Capacity
Up to 1.5 m³/hour
Output varies significantly depending on sieve size and material type — factor this in when sizing against your actual waste volumes.
Motor Power
15 kW
Requires a 400V three-phase supply with a minimum 32A fuse — confirm your site supply before ordering.
Feed Hopper Opening
620 × 430 mm
Sieve Sizes
10 / 12 / 15 / 20 / 30 / 40 mm
Four sieves are included as standard; confirm with IWM which sizes are supplied and which are optional extras.

Feed Hopper Opening
620 × 430 mm
Sieve Sizes Available
10 / 12 / 15 / 20 / 30 / 40 mm
Smaller sieves produce finer output suitable for briquetting; larger sieves increase throughput but yield coarser material.
Capacity
Up to 1.5 m³/hour
Throughput depends on sieve size and material — actual rates in mixed-material operations will vary.
Suitable Materials
Waste wood, plastic, paper & cardboard, packaging, agricultural waste, electronic cables
Dimensions (L × W × H)
949 × 1083 × 2109 mm
Allow additional clearance around all sides for feed access, extraction connection, and maintenance — the 2,109 mm height should be checked against your ceiling and any extraction ductwork.
Weight
920 kg
At this weight, floor loading capacity should be checked with a structural engineer before installation.
Control System
Unitronics® PLC
Remote Access Option
Optional — Resmart™ intelligent control system
Remote access allows fault monitoring and process adjustment without being at the machine, which can be useful in unmanned or partially attended processing areas.
Output Container
Stainless steel
Cable Length
10 m
The 10-metre cable gives reasonable flexibility in positioning the machine relative to your electrical supply point.
Hopper Insulation
Yes — insulated hopper for reduced noise during feed
The insulated hopper dampens impact noise when loading material, which can meaningfully reduce operator noise exposure over a shift.
Hopper Safety Cover
Yes
Warranty
4 years or 1,500 hours
The dual warranty trigger means high-use operations may reach the hour limit before the time limit — factor your expected annual hours into this.

Is this the right
machine for you?

Choose the Robust Lab SD450 Shredder if...

  • You need a single machine capable of handling a variety of materials — wood, plastics, cardboard, and packaging — rather than a wood-only shredder
  • Your throughput requirement is moderate and up to 1.5 m³/hour is sufficient for your waste volumes
  • Output particle size needs to vary by application, and the ability to swap between six sieve sizes is operationally important
  • Floor space is constrained and you need a compact footprint without sacrificing rotor working length

Consider an alternate model if...

  • Your volumes consistently exceed 1.5 m³/hour — the Robust SD600 or SD700 would be better suited to higher-throughput operations
  • You process exclusively wood waste and want a machine optimised for that material — the Robust REUSER SD450 Wood Shredder is purpose-built for wood and may offer better performance in that application
  • Your material is lighter or lower-density and a smaller machine would suffice — the Robust SD90 or SD90 XL may be more appropriate and more economical to run
  • Budget is the primary driver and a simpler, lower-powered shredder would meet your actual processing demands — talk to us and we will help you right-size the specification
