Pre-Shredder FORUS F 25

Slow-Running Shredder with Two Shafts for Shredding Refuse, Waste and Wood

You may rely on the support of professional equipment for shredding and blending of commercial or electronic waste, or plastic sheet or paper?

Or you could be running an agricultural contracting business for the treatment of wood and biomass and are looking for a suitable pre-shredder for material pre-treatment? Alternatively, you might be specialised in shredding and composting of grass and tree cuttings and wish to optimise your plant and equipment? Whatever you need, we can solve the problem! The FORUS F 25 slow-running pre-shredder is an appropriate choice for the efficient shredding of a wide variety of materials.

The FORUS F 25 pre-shredder is suitable for all types of refuse and wood. Household, bulk, or commercial waste, plastic sheet, paper and electronic waste are shredded just as effortlessly as reclaimed and demolition timber, green waste and root stocks. The final particle size varies from 0 to 500 mm, and is always dependent on the input material and the crushing beam selected. This can be raised and lowered hydraulically and is available from type A1 to A5, depending on requirements.

The final grain sizes and throughputs of the shredder can be adjusted and optimised from 0 mm to 500 mm within just 10 minutes, depending on the application, by means of a hydraulic, modular secondary crushing beam system.

Pre-Shredder in individual versions

The shredding unit of the mobile shredder can be easily adapted to the material and the required final particle size. The tools for the two rotors, the planetary gears for the drive and the type of crushing beam can be freely selected. Both rotors are independent from each other in their rotating direction and rotational speed.

With a vloume of 4 m³ the large lift hopper allows for quick and easy filling of the pre-shredder by wheeled loader or excavator. The magnet, above the belt of the slow-running unit is also included. This can also be moved or adjusted using the hydraulic system. Similarly, the discharge system allows for a material discharge height of 3,200 mm.

Service and maintenance are an easy task with the FORUS F 25 pre-shredder. The generous maintenance doors ensure easier access to all components associated with inspection. And even changing the crushing shaft is not an issue with this machine. 

The simple, user-friendly and intelligent control design ensures maximum machine availability with optimum utilisation. The performance and fill level parameters as well as error messages and maintenance intervals are displayed digitally and ensure trouble-free and reliable machine operation or shredding process.

Waste wood treatment

Waste wood categories A1 through A4

The treatment of waste wood can be done within two processes: Either by mere shredding of the material or by shredding and subsequent sieving.

Treatment of green cuttings

Composting of green waste

Composting of organic residues leads to a valuable, nutritious product for soil improvement. Organic material gets returned to the biological cycle and is not irretrievably lost as it would be the case with thermal processing. The process chain for composting of green cuttings consists of shredding, turning, screening and sifting.

Treatment of bulky waste

Bulk waste processing

Bulky waste is processed by shredding the material and relieve it of metals. Then it is screened to filter out e.g. plastics.
