All M&J PreShred units feature a modular design approach combining a range of
well-proven components to meet your specific application and shredding performance. Metso Denmark’s range of stationary shredders includes four machine types covering a wide range of capacities. Each model is available in a variety of shredding performance levels. Our stationary units are suitable in a wide range of different applications.


  • Open cutting table reduces wear to the bare minimum
  • Bi-directional shredding results in a consistent flow of shredded material onto down-stream conveyors
  • Asynchronous shredding keeps waste constantly moving, thus improving shredding efficiency
  • With our aggressive knife design, no pushing device is required
  • Central lubricating system is standard on all machines
  • Automatic reversal if knives encounter large or tough steel cement parts
  • Intelligent shredding routines automatically adapt to processed material characteristics. The PLC control system is equipped with six standard programs, including two that can be individually programmed
  • Hardox steel used in all parts of the cutting table exposed to wear
  • Bi-directional shredding with equal speed and torque reduces wear and improves capability and pre-shredder capacity

The best choice in your plant

RDF lines

Waste is considered a potential energy source where stationary PreShredders play an important role. Most plastic and paper waste Refuse Derived Fuel (RDF) plants have specific requirements regarding shredding capacity, grain size and operating reliability to ensure reliable and consistent production. The RDF technology is used at e.g. Waste-to- Energy (WTE) plants, gasification plants, cement kilns etc.


Companies engaged in biomass processing are increasingly adopting stationary shred­ders to increase the delivery of consistent, specific carbon-neutral biomass energy products. This selected fuel is attractive to operators of incineration facilities who are keen to reduce their overall carbon emissions.

Waste-to-Energy (WTE)

Worldwide focus on recovering as much energy out of waste as possible, has led to waste pro­cessing being an important growth market for shredder technology at WTE plants. Numerous technologies now exist to produce fuels and energy from waste. Incineration is the most common WTE conversion but to maintain a consistent flow, increase combustion efficiency, improve emission and reduce costs, it is essen­tial that the waste is pre-shredded. Input could be Bulky, Industrial (C&I), Hazardous, Household (MSW), Wood, Construction and Demolition (C&D), Biomass as well as baled materials like straw.

MBT plants

Mechanical Biological Treatment (MBT) compa­nies can increase recycling opportunities when using Metso shredders. By combining Metso stationary PreShredders with Metso FineShred­ders, a perfect RDF can be produced, thus ensuring a maximum recovery of material
