3C Rotary Feeder

The 3C Rotary Feeder enables the processing of materials with low bulk density without external, upstream processing steps.

3C Rotary Feeder

To process materials with a low bulk density without external, upstream processing steps, the system consists of a shredder, a conveyor belt and the 3C Rotary Feeder. In the shredder, the material is pre-shredded if necessary and then fed to the 3C Rotary Feeder in a timed sequence by the conveyor belt. A disk with cutting elements rotates in the drum of the 3C rotary feeder, cutting, compacting and heating the material. As a result of the energy supply, the surface moisture is removed from the material before the extrusion step, thus helping the plasticizing process. The material transfer between the 3C Rotary Feeder and the extruder is fully automatic and results in consistent extrusion conditions even with fluctuating input qualities.

In this way, a very wide range of materials can be processed on the machine, as the combination of “cutting”, “compacting” and “conditioning” before the MRS extrusion process creates a very large process window. The spectrum here ranges from foamed PS blocks to fiber bales, for example. In combination with the unique MRS Extruder, this results in an optimum solution for plastics recycling.
