Blend of plastics with wood particles

A method for producing a blend of wood particles and/or other plant particles in an extrusion line that includes a feed part 201, a melting device, an introduction pump and at least one planetary roller part 202 that has a central spindle, multiple planetary spindles, a surrounding housing, with the multiple planetary spindles rotating around the central spindle in the housing as a result of an internal toothing of the housing, said method comprising the steps of:

• feeding the wood particles and/or other plant particles into the feed part 201, the wood particles and/or plant particles having a maximum size of 1 mm;
• feeding the plastic particles into the melting device and then, independently of the wood particles and/or other plant particles, liquefying the plastic particles into a plastic melt;
• feeding the plastic melt into the introduction pump;
• advancing the wood particles and/or other plant particles out of the feed part 201 and into the planetary roller part 202,
• injecting the plastic melt into the planetary roller part 202 containing the wood particles and/or other plant particles, such that the wood particles and/or other plant particles have a proportion of at least 60% by weight in the blend;
• blending and homogenizing the plastic melt with the wood particles and/or other plant particles in the planetary roller part 202;
• compacting the blend in the planetary roller part 202;
• and
• discharging the blend out of the extrusion line.
