Multimode twin polymer mixer
Pellets are produced in “natural” or “black” grade, one mixing & extrusion line can only produce one grade. There is no ability to change the grade without significant effort.
Koellemann’s new Multimode Twin Polymer Mixer is the world’s first device capable of mixing white or colored polymers without the need for an expensive cleaning process.
It is the first mixer available on the market, which allows to mix different colors in one machine.
Polymer additive mixer-In natural mode of operation:
The powder is mixed with additives and is discharged via the natural outlet, the outlet-width is big enough to ensure no powder will pass into the black section and interfere with the closed outlet.
The screw flights in the transition section will ensure that no carbon black particles can fall back (due to vibration or gas flow) into the clean natural section of the mixer.

Polymer additive mixer-In black mode of operation:
The “natural” outlet is closed, the discharge portion is filled with material and will not affect the conveying into the “black” zone. Carbon black is added and mixed in by a second set of mixing-tools. Discharging is done via the “black” outlet.
We offer an additional bag filter with automatic, differential pressure-controlled cleaning placed in the outlet area to avoid any overpressure in the product chamber due to upstream or downstream components and due to the nitrogen application. All instruments required are housed in a user-friendly, protective and visually appealing stainless-steel control cabinet.
