3C Rotary Feeder
The newly developed 3C Rotary Feeder makes it possible to use low bulk density materials without any external processing steps. A conveyor belt feeds shredded reclaim material into the hopper, where a fast-rotating disc with knives cuts, compacts and pre-conditions the material. The knives add energy into the material and start the heating and degassing process before the material is automatically fed into the extrusion system.
Depending on the application, the OMNImax series uses either a modified MRS extruder with a longer multiple screw section or an MRSpure. In contrast ot the OMNI series, the MRS extuder used in the OMNImax has an extended multiple screw section, which ensures efficient and gentle degassing of the polymer at 1-2 mbar and meets requirements for direct food applications. The mutliple screw section also ensures a very effective homogenization of the melt. The large polymer surface enables highly efficient decontamination, mixing and viscosity control, especially with polyester, thus achieving high-quality end products such as packaging sheet, strapping or filaments.
For higher viscous polymers, an MRSpure-Extruder is used, with a melting extruder installed upstream of the multiple screw section. Depending on the requirements, a single or twin screw extruder can be used for melting. The MRSpure is used e.g. in closed-loop recycling of HDPE bottle caps, HDPE milk bottles or LDPE waste.
