Pre-shredders

Pre-shredders

For efficient operations in numerous waste recycling applications

Pre-shredders are efficient waste processing machines utilized in recycling and waste processing applications. Available as stationary or mobile versions, pre-shredders can process various waste types ranging from municipal solid waste to biomass, industrial, commercial or bulky waste.

Process multiple materials

Bulky waste, commercial and industrial waste, municipal solid waste, construction and demolition waste, biomass, wood, baled materials.

Diverse applications

Residue-derived fuel (RDF) production, biomass processing, waste-to-energy plants (WtE), mechanical biological treatment plants (MBT).

Stationary pre-shredders

Sizes and capacities range from small to large depending on the requirements.

Mobile pre-shredders

Efficient waste shredding wherever you need it. Easy to move and transport.

Reliable pre-shredders for businesses of any size

Pre-shredders can process multiple waste types such as bulky waste, commercial and industrial waste, municipal solid waste, construction and demolition waste, biomass, wood, as well as baled materials.

Pre-shredders are often utilized in residue-derived fuel (RDF) production, biomass processing, waste-to-energy plants (WtE), and in mechanical biological treatment plants (MBT).

Metso’s pre-shredders offering contains both stationary and mobile pre-shredders.

Stationary pre-shredders

Stationary pre-shredders are the optimal choice in applications where mobility of equipment is not required. Metso’s stationary pre-shredders range is divided into two different product families according to size. M&J K-Series pre-shredders are smaller in size and capacity, while M&J PreShred Series pre-shredders are larger in physical size and have higher throughput.  

M&J K-Series pre-shredders

M&J K-Series is the latest addition to Metso’s wide range of waste shredders. Designed especially for sites with a 5-45 tons per hour production requirement, M&J K-Series pre-shredders are the most compact models of stationary pre-shredders.

M&J PreShred Series pre-shredders

M&J PreShred Series product family consists of both stationary and mobile pre-shredders. Thanks to their larger size and higher shredding power, M&J PreShred Series equipment can process more material and reduce also very bulky objects efficiently.

Mobile pre-shredders

Mobile pre-shredders are equipped with the same shredding units as M&J PreShred Series stationary pre-shredders. However, different mobile pre-shredder models are built either on crawlers or a trailer, which makes them easy to move at a production site or transport between sites when needed.

Stationary pre-shredders

The shredding technology of stationary pre-shredders is based on aggressive knife designs and open cutting tables.

These distinct technical features provide outstanding performance when dealing with mixed and challenging materials.

Stationary pre-shredders are extremely resistant to wear caused by waste materials normally considered as non-shreddable, such as solid steel, reinforced concrete, and rocks. 

Mobile pre-shredders

M&J PreShredder Series mobile pre-shredders utilize the same shreddig technology as the stationary pre-shredders. 

Different models are either track-mounted (on crawlers) or wheel-mounted (on trailer). 

Mobile pre-shredders as efficient as stationary ones, but thanks to the undercarriage, they are easily transportable at a production site or between sites.
