Its novel blade separation and cutting geometry guarantees optimal shredding with high energy efficiency, according to the German company.
The F-Rotor has been designed in such a way that the full extent of the rotor engages completely with the stator blade and quickly shreds the material. Its markedly narrower cutting gap compared to earlier versions is said to result in controlled feeding of input material to prevent wrapping around the rotor.
Resultant flakes are squeezed through the screen perforations in a highly-compressed form and subsequently expand to their original volume. In order to avoid this process leading to blockages, the machines are designed with an exposed screen basket so that flakes fall onto the conveyor belt installed underneath the machine without being forced by pressure. Product can be processed directly without further treatment on an extrusion line.
The rotors sit entirely in recessed rotor bearings in such a way that penetration of material and consequent damage to the bearings are prevented. The machine’s screens are made according to customer requirements with perforations of between 30 and 100mm. The F-Rotors are used with working widths of 800 mm to 3000 mm and with rotor diameters of 368 mm to 600 mm. This single-shaft shredder comes with the option of electromechanical, hydraulic and direct drive.
