Abstract

Method for producing a blend of a plastic first material and a wood or other plant second material in a planetary roller extrusion arrangement. The method involves feeding particles of the second material into a feed, which particles of the second material have a maximum diameter of 1 mm. Particles of the first material are fed into a melting device and liquefied into a plastic melt. The plastic melt is fed into a pump. Particles of the second material are moved into a planetary roller part of the extrusion arrangement, while the plastic melt is also pumped in. The particles of the second material are then blended with the plastic melt to form a blend that is at least 60% by weight of the second material.
