Ravne Systems
Shredder knives from Ravne Systems
Rotor knives, stator knives and knives for size-reduction plants. INDUSTRISTÅL enquires with Ravne Systems on machine, dimensions and the fraction the plant runs. The programme is called SIKNIVES.

Rotor knives and stator knives
The shredder cuts volume down. Rotor and stator knives, block knives and hammers follow the machine and the fraction – municipal and industrial waste, WEEE, tyres, plastics, paper, cables, wood, textiles and batteries. We do not state a hardness until the fraction is known.
Wear parts for recycling machines
Knife holders, screens, screws, washers, nuts and wear plates can accompany the knife. They are Ravne's own parts for the machine, not a spare parts catalogue from the machine builder.
Custom manufacture to drawing
If you have a drawing, a photo or the existing knife, we use it. State make and model if you know them. The name locks the dimension – it does not make us the OEM.
Not an original spare part
SIKNIVES is Ravne Systems' own programme. INDUSTRISTÅL and Ravne are not the machine builder and not an authorised dealer of the machine make. A machine name is used to match drawing and dimensions – it is not a promise of an original spare part.
Frequently asked questions
- Is the shredder knife an original spare part from the machine builder?
- No. SIKNIVES is Ravne Systems' own programme. INDUSTRISTÅL represents Ravne in Denmark and is not an authorised dealer of the machine make.
- What do I need to send to get a quotation?
- Company, contact, machine make and model if you know them, dimensions, quantity and preferably a drawing, a photo or the existing knife. Material requirements only if you already know them.
- Do you also know the English names?
- Yes. Shredder knives, rotor knives and stator knives are the same parts. German enquiries often say Schredder-Messer.
