1956: The first machine with a vertical rotor was developed
1965: The Alpine Rotoplex Ro granulator rolls off the production line in its “current” form with a vertical rotor for the first time in Augsburg
seit 1965: Introduction & Export to markets worldwide
1972: The Rotoplex is used for the first time for shredding cable waste
1984: Further development with patented cross-shear cut (lower load peaks and even wear)
1988: Development of the largest rotor diameter in Rotoplex history to date: the Alpine Rotoplex Ro 125/125
2003: Further development of the Rotoplex for wet grinding operation
2024: Optimization of the rotor for recycling fibres and textiles
