Tearing fan with replaceable cutting strips on the impeller blades

The processing of excess continuous material

With tearing fans, we can shred continuous material such as edge strips which arise, for instance, during the manufacture of paper, cardboard and fibreboards. The fan’s design is dependent on the width of the edge strips, the roll-off speed and the type and thickness of the material. The tensile strength and coating of the waste are also determined and used in the calculations. The impeller blades are fitted with replaceable cutters or saw-strips, with which the continuous strips are shredded.
