Rotary and stator knives for glass fibre recycling

Crushing at the highest level: Our granulating knives for glass fibre

Challenge overcome

Glass fibre is used in technically demanding fields such as telecommunications or the automobile industry, in particular. After use, these products must be recycled, in order to be used in the manufacture of new glass fibre products. The extremely abrasive glass fibres place enormous demands on crushing. In addition to standard qualities, we therefore make a variety of special qualities, in order to increase the working life of the knives and reduce the number of changes required.
