High-quality Production of Toner

Coperion is longtime expert in the design and implementation of feeding and extrusion systems for high-quality toner. Toner recipes consist of resins, pigments and additives, which need to be handled very gently and at the same time thoroughly mixed.

These components are first processed in a mixer to form a premix. The premix is fed continuously via a volumetric feeder into the Coperion twin screw extruder ZSK.

The closely intermeshing, co-rotating screw shafts of the extruder pick up the product, convey and compress it and finally melt it with the kneading elements in the plasticizing zone. The individual components of the mixture are dispersed, mixed and homogenized during and after the melting process.

The processed melt is discharged through a nozzle  and is immediately cooled  down and broken as a preparation for the following grinding process.
