A multi-shaft extruder has at least six worm shafts (4) between an exterior housing (9) and an interior housing (10), wherein the worm shafts are disposed in a circle (7). The drive (1) of the multi-shaft extruder has two pinion shafts (2), which are partitioned into groups of identical design and disposed on a circle, the shafts being radially driven from the inside and the outside at equal forces and in the same direction, and are disposed diametrically opposed from each other. The shafts are coaxially connected to the worm shafts (4) of the process part (5) via couplings (3), wherein the worm shafts (4) have a feed length (L) of at least six Do, and a Do/Di ratio of 1.5 to 1.93, wherein Do represents the outside diameter and Di represents the inside diameter of the feed screws (11, 12, 13), and the torque density of the extruder is at least 50 Nm/cm3. |
