Robust M&J F320 fine-shredder delivering high capacities

Equipped with a unique cutting system

The low operating costs are due to an innovative design. The M&J F320 has a unique cutting system that requires minimal daily maintenance. Once the rotor knives and static knives have been set in the initial setup, or after a change of knife holders, it does not require routine adjustment like other competitors. The M&J F320 also generates a limited amount of heat, so you can avoid frustrating downtime due to, for example, molten plastic. Stable and flexible production are key words for the M&J F320. You just set the output size and adjust the pusher to meet your needs and off you go.


Modular design ensures fast servicing

A unique feature of the M&J F320’s construction is the well-thought-out location of wear parts. The service team has quick and easy access to everything and can therefore replace all wear parts extremely quickly to avoid lengthy maintenance. There is easy access to the shaft from both sides for servicing and cleaning – and the knife blocks have been designed for easy replacement, should the need arise. The maintenance time is reduced by up to 2/3 compared to our competitors, offering higher production yield and significant running cost benefits.

Single rotor fine-shredder
The M&J F-series offers leading cutting technology and a cleverly designed rotor.

This means high-efficiency FineShredding of qualified materials, making it particularly suitable for the production of alternative fuels like RDF/SRF.

The FineShredders deliver a homogeneous output in the desired size. In addition, the machines leave a very small number of undesired fines.
