The Rotoform family
The experience we have gained in steel belt-based granulation has enabled us to adapt, develop and improve upon the Rotoform concept, building solutions to a range of new chemical processing applications.

The basic principle remains unchanged – the efficient processing of a melt into solid pastilles – but an entire Rotoform family has now been developed to allow the production of pastilles from virtually any meltable chemical and a wide range of food products.
The development of this comprehensive product range has not only led to faster and more efficient pastillation, it has also opened up new opportunities for chemical processing. In the past, certain melts have proved impossible to process. Some need an extremely high melt temperature of up to 320°C; some demonstrate abrasive, sedimenting or corrosive properties; and still others fall into the category of supercooling melts.

With the right Rotoformer configuration it is now possible to produce pastilles out of chemical melts with any of these extreme and demanding requirements.
