The Rotoform 4G MC (Micropastillation) has been specially developed to enable the production of pastilles as small as 1 mm diameter directly from the melt, avoiding the need to grind or crush larger granules.
Pastilles of this size, known as micropastilles, have the advantage of being easier to dissolve, mix or dose in subsequent reprocessing.
In this system, the distance between the surface of the outer shell of the Rotoform and the steel belt is so small that pastilles do not fall by gravity but are taken onto the steel belt through simple adhesion. The gap between the outer shell and
the steel belt is therefore critical to the successful operation of this process, and the Rotoform 4G MC incorporates special devices for the easy and accurate adjustment of its position in relation to the surface of the steel belt.
This process is suitable for any type of product that is already being formed into pastilles, granules or pellets, including:
- Hot melt adhesives
- … and many others
This system also provides outstanding flexibility, offering quick and easy changeover to the production of normal pastilles (from 3-8 mm diameter).
