Description A design of dielectric barrier discharge plasma source suitable for treatment of bulk materials is described. The design is based on shaftless screw conveyor. It combines both the surface and volume dielectric barrier discharge and operates at atmospheric pressure. Rotational movement of shaftless spiral helps transporting and simultaneously mixing particulate material through the discharge zone. The machine was tested on plasma treatment of PET flakes in order to increase its surface free energy. To optimize the parameters of plasma treatment the measurement of chemiluminescence signal was used. Plasma treated PET flakes were used as an additional filler of wood-based particleboards. Particleboards containing plasma treated PET flakes showed substantially better mechanical properties than composite particleboards containing non-treated PET flakes.
