Features

  • At the core of the MR shredder’s rugged design, the C cutting system is designed to tackle a wide variety of materials other machines simply can’t handle, from thick-walled plastic sprues and moulded parts to IBC containers and strapping bands. It’s therefore ideal for plastics processors, compounders, recycling companies, and industrial production facilities alike. The system’s large rotor diameter ensures reliable material intake, while bolted blade holders allow the cutting unit to be precisely configured – with up to three blade rows and 101 cutting blades – to suit virtually any application.

  • The beltless asynchronous direct drive with planetary gearbox and maintenance-free safety clutch operates without tensioning mechanisms, shaft stubs, or a flywheel. Mechanical wear is reduced, and maintanance requirements are significantly minimised.

  • The 7-inch touchscreen display enables direct and intuitive operation of the machine. Operating statuses, error messages and key parameters are clearly visible at all times and can be adjusted quickly and easily. The user-friendly interface simplifies daily operation and enhances overall process reliability.

MR Benefits

Demanding applications meet their match with the MR Class

Direct maintenance access

The shredder’s hydraulic service door opens directly into the cutting unit, making blade changes, foreign object removal, and thorough compartment cleaning fast and straightforward.

Precise particle control

Interchangeable perforated screens deliver homogeneous particle sizes from 10 to 60 mm, letting you tailor output quality precisely to the demands of your recycling process.

Consistent, controlled feeding

The maintenance-free feed pusher intelligently regulates material flow, achieving a throughput of 1–5 tons per hour while utilising the full rotor width – ideal for baled material.

Simplified screen changes

The lowerable screen basket enables single-operator screen changes while three identical, interchangeable segments streamline spare parts management and reduce inventory costs.

Built for bulky materials

The large-capacity loading hopper accommodates even the most unwieldy inputs, handling bulky waste efficiently with a telescopic loader or dedicated material-handling equipment.

Robust machine construction

Torsion-resistant profile tubes deliver exceptional stability and minimal vibration, protecting equipment under even the most demanding, high-throughput operating conditions.

What the MR can shred

The MR1800C PRO is a universal shredder that steps in when other machines reach their limits, tackling complex waste streams like plastic sprues, moulded parts, pipes, profiles, bales of film, and waste wood with exceptional control and efficiency.

MR Class FAQs

If you still can’t find the answer you’re looking for, reach out to our customer support team  – we’re happy to help.

  • The MR1800C PRO is built for applications where other machines reach their limits. With a 1,800mm cutting width, 110kW direct drive, and safety clutch, it handles the toughest materials – including thick-walled plastics, pipes, and composite materials – without pre-treatment.

  • The MR shredder processes plastics of all types (such as sprues, moulded parts, pipes, IBC containers, film bales), waste and residual wood, paper and cardboard, textiles, composite materials, pallets, and confidential files across demanding multi-shift operations.

  • The machine’s intelligent external feed pusher delivers a consistent throughput of 1–5 tonnes per hour, ensuring controlled material feed even with bulky, high-volume, or difficult-to-grip inputs – without loss of performance.

  • Screens swap in under 15 minutes by a single operator, and the hydraulic service door allows upright cutting unit access with restart in under two minutes. Meanwhile, real-time machine data, maintenance scheduling, and spare parts identification are all available via the MyUNTHA customer portal.

  • Perforated screens allow precise control of output particle size from 10 to 60mm, ensuring homogeneous, defined fractions tailored to downstream recycling or processing requirements.

  • UNTHA Finance offers flexible procurement packages including hire purchase, finance lease, operating lease, contract hire, and asset refinance. Whether you want to own the equipment long term or prefer a fully managed solution with servicing included, there's a structure to suit your operation and cashflow needs.
