    Robust REUSER SD700 Shredder

    Robust
    A hydraulic-fed, single-rotor shredder built for workshops and processors that need to reduce significant volumes of wood waste to a consistent, usable fraction day in, day out. Sized above the SD600, it suits operations where throughput, wear-part economy, and straightforward servicing all matter.

    Typically chosen by

    • Timber processors and sawmills generating significant volumes of offcuts, slabs, or dimensional waste that need reducing to a consistent fraction
    • Joinery and panel shops looking to reclaim floor space and reduce skip costs by shredding bulky wood waste in-house
    • Waste and biomass contractors who need a robust, serviceable machine capable of handling mixed or contaminated wood streams

    Key specification considerations

    Throughput
    Approx. 3–5 m³/h
    Actual output depends on material type and the sieve aperture selected — denser or wetter timber will sit toward the lower end of this range.
    Cutting System
    Hardened knives — four cutting edges per knife
    Four-edge knives can be rotated before replacement, significantly reducing knife running costs over time.
    Sieve Material
    HARDOX wear-resistant steel
    HARDOX is a recognised abrasion-resistant steel grade; a HARDOX sieve extends service intervals compared to standard steel alternatives.
    Control System
    BOVER_BASIC intelligent control with star/triangle motor start
    Star/triangle start-up reduces inrush current at motor start, which may affect your electrical supply sizing — confirm with your electrician before installation.

    Manufacturer
    Robust
    Control System
    BOVER_BASIC intelligent control system
    Drive System
    Electric motor with reduction gear and belt transmission
    Hydraulic System
    Hydraulic pressure unit included
    The hydraulic ram feeds material into the cutting chamber under controlled pressure, helping to maintain consistent throughput with irregular or bulky feed material.
    Filling Hopper
    Included
    Filling Hole (L × W)
    1,445 × 1,345 mm
    This is the clear aperture of the feed opening — allow sufficient overhead clearance above this height for loading by excavator, forklift, or lift arm.
    Knife Specification
    Hardened knives with four cutting edges — extended service life
    Four-edge knives can be indexed rather than replaced when one edge dulls, lowering consumable costs.
    Cleaning Knives
    Hardened cleaning knives included
    Cutting Racks
    Hardened cutting racks
    Sieve
    HARDOX sieve
    HARDOX construction extends sieve life in abrasive or contaminated wood waste applications.
    Available Sieve Sizes (hole diameter)
    10–50 mm
    Sieve aperture directly controls output fraction size — a smaller aperture gives a finer chip suitable for briquetting; a larger aperture maximises throughput rate.
    Motor Start Method
    Star/triangle (soft-start)
    Confirm your site's electrical supply capacity with your installer before ordering.
    Motor Power
    15 / 18.5 / 22 kW (options)
    Three motor sizes are available — the appropriate choice depends on your throughput requirements and site electrical capacity; discuss with IWM at the point of specification.
    Minimum Fuse Rating
    50 A
    Verify this requirement with your site electrician before installation; the star/triangle start method reduces peak demand but a dedicated circuit is still required.
    Throughput / Output Rate
    Approx. 3–5 m³/h
    Output is dependent on material density, moisture content, and selected sieve diameter — confirm expected throughput for your specific waste stream with IWM.
    Rotor Working Length
    650 mm
    Rotor Diameter
    270 mm
    Machine Dimensions (L × W × H)
    1,920 × 1,550 × 1,790 mm
    Allow additional clearance beyond these footprint dimensions for extraction ducting, material infeed, and operator access — a minimum of 1 m clearance on all working sides is advisable.
    Machine Weight
    1,750 kg
    At this weight, floor loading capacity should be checked before installation, particularly in older timber-framed or mezzanine-level premises.
    Noise Level
    Consult IWM
    Noise output varies with motor size, material type, and sieve selection — ask IWM for guidance on acoustic treatment or hearing protection requirements for your specific configuration.

    Is this the right
    machine for you?

    Choose the Robust REUSER SD700 Shredder if...

    • Your waste volumes have outgrown a mid-range shredder and you need the additional capacity and robustness of the SD700 over the SD600
    • You are processing dense, knotty, or irregular timber waste where a hydraulic feed system and heavy-duty cutting geometry will provide more consistent results
    • Knife and wear-part running costs are a concern — the four-edge knife design and HARDOX sieve make this a more economical machine to maintain at high utilisation
    • You need a machine that can be adjusted and serviced in-house, with a straightforward control system that your operators can manage without specialist training

    Consider an alternate model if...

    • Your volumes are more modest — the Robust REUSER SD600 or REUSER SD450 Wood Shredder may be appropriately sized and represent a lower capital cost for lighter-duty applications
    • You are shredding relatively clean, consistent timber offcuts in a smaller workshop — the Robust SD90 XL or SD90 Shredder may be sufficient and will take up considerably less floor space
    • You need shredding capability for evaluation, sampling, or low-volume trials — the Robust Lab SD450 Shredder is designed specifically for that purpose
    • Budget is the primary driver and your feed material is not particularly abrasive or contaminated — talk to us about whether a lighter-spec machine would serve you adequately
