    Robust SD90 XL Shredder

    Robust
    A step up from the standard SD90, the XL gives joinery and timber workshops a wider hopper opening and higher throughput capacity to keep pace with busier production lines — without moving to a much larger machine.

    Typically chosen by

    • Joinery and timber processing workshops that have outgrown smaller shredders and need a machine that keeps pace with production waste
    • Operations handling bulky or irregular offcuts that require a larger hopper and hydraulic feed control to process efficiently
    • Businesses looking to reduce waste haulage costs by shredding on-site to a consistent particle size for disposal or reuse

    Key specification considerations

    Throughput Capacity
    5–8 m³/h
    Output varies with material type and the sieve aperture selected — denser hardwoods or smaller sieve holes will sit toward the lower end of this range.
    Motor Power
    18.5 / 22 / 30 kW (three options)
    All motor options require a three-phase supply; confirm your site's available amperage with your electrician before specifying the motor size.
    Hydraulic Feed System
    Hydraulic pressure unit included
    The hydraulic feed unit controls material pressure against the cutting rotor, reducing jams and allowing the machine to self-regulate through denser or irregular loads.
    Sieve Material
    HARDOX wear-resistant steel
    HARDOX is a wear-resistant steel — a sieve made from it will outlast standard steel sieves significantly in abrasive wood waste applications.

    SpecificationValueNotes
    Model
    Robust SD90 XL
    Control System
    BOVER BASIC intelligent control system (BOVER PREMIUM available as upgrade)
    The intelligent control system monitors load and can reverse or pause the rotor automatically — reducing operator intervention and protecting the drive components.
    Drive System
    Electric motor, reduction gear, and belt transmission
    Motor Power
    18.5 / 22 / 30 kW (three options)
    Motor size is selected at point of order; discuss your duty cycle and shift pattern with us to ensure the right motor for your application.
    Electrical Supply
    Three-phase (confirm site amperage with your electrician for the motor size specified)
    Amperage requirement varies depending on which motor option is selected — verify your site supply is adequate before ordering.
    Motor Start-Up
    Star/triangle (star-delta) starting system
    Star-delta starting reduces the inrush current at start-up, which matters if your site has limited electrical capacity or you are running other machinery on the same supply.
    Hydraulic Unit
    Included
    Hopper Opening
    2030 × 1565 mm
    The XL's hopper opening is approximately 585 mm wider than the standard SD90 (1445 × 1565 mm), which is the key practical difference for workshops feeding longer or bulkier timber pieces.
    Filling Hopper
    Standard (larger hopper available as upgrade)
    Rotor Working Length
    870 mm
    Rotor Diameter
    270 mm
    Knife Configuration
    Hardened knives with four cutting edges
    Four cutting edges per knife means each knife can be rotated three times before replacement is needed, reducing tooling costs over the machine's life.
    Cleaning Knives
    Hardened cleaning knives included
    Cutting Racks
    Hardened cutting racks
    Sieve
    HARDOX sieve
    HARDOX is a wear-resistant steel — a sieve made from it will outlast standard steel sieves significantly in abrasive wood waste applications.
    Output Particle Size (Sieve Hole Diameter)
    10–50 mm (sieve aperture selectable)
    The sieve aperture you select determines the output particle size — smaller holes give a finer chip suitable for biomass or briquetting, larger holes increase throughput.
    Throughput / Capacity
    5–8 m³/h (material and sieve aperture dependent)
    Output varies with material density and moisture content; discuss your specific waste stream with us for a realistic throughput estimate.
    Weight
    2,450 kg (machine only); 4,200 kg with interface cabinet and P150 pre-shredder
    At 2,450 kg and above, floor loading capacity should be checked with a structural engineer before installation.
    Overall Machine Dimensions (L × W × H)
    Contact IWM — dimensions vary by configuration and are confirmed at point of order
    Allow additional clearance on all sides for infeed access, extraction ducting, and safe operator movement around the machine.
    Noise Level
    Contact IWM — noise data is confirmed at point of specification
    Shredders of this class typically require acoustic consideration; discuss your installation environment with us, particularly if the machine is in or adjacent to an occupied workspace.
    Operator Interface
    SPS wheeled cabinet with touchscreen
    Optional Upgrades
    BOVER PREMIUM control system; larger filling hopper; pre-shredder P150
    The P150 pre-shredder is worth considering if your waste stream includes large or unsorted timber pieces that would otherwise require manual breaking down before feeding.

    Is this the right
    machine for you?

    Choose the Robust SD90 XL Shredder if...

    • Your waste volume has grown beyond what the standard Robust SD90 can handle comfortably in a shift
    • You regularly feed bulky or long timber offcuts and need the larger hopper opening the XL provides
    • You want a machine with an intelligent control system that can self-manage rotor load rather than requiring constant operator attention
    • You anticipate future growth and want the option to add a pre-shredder (P150) or upgrade the control system without replacing the machine

    Consider an alternate model if...

    • Your waste volumes are modest or intermittent — the Robust SD90 (standard) is the more proportionate choice and will cost less to run and maintain
    • You are processing very high volumes of mixed or large timber waste and need significantly greater throughput — the Robust REUSER SD450 or SD600 may be more appropriate at that scale
    • You need a machine for a research, training, or low-volume environment — the Robust Lab SD450 is specifically configured for lower-intensity use
    • Budget is the primary constraint and the XL specification exceeds what your current waste stream justifies — talk to us and we will help you right-size the machine
