Abstract
Kneading device for high-consistency fiber pulp that includes at least two substantially rotationally symmetrical and coaxial kneading machines, that are movable relative to each other. The kneading machines may include teeth in ring-shaped tooth rows forming ring shaped gaps between the tooth rows and positioned relative to one another such that at least one tooth row of one of the at least two kneading machines reaches into the ring-shaped gaps of an other of the at least two kneading machines. A face side of at least a portion of the teeth may include an angled surface for diverting the fiber pulp in a transport direction, provided by a throughput of a flow of the fiber pulp through the kneading device and by relative movement between the fiber pulp and the face side. At least a portion of the teeth may include angled surfaces on a rear side. An angle .alpha.1 of a slope on the face side may differs from an angle .alpha.2 of the rear side by at least 5.degree., and at least a portion of the teeth may be mounted in a releasable fashion, so that a position of the face side and the rear side may be exchangeable by rotating the teeth.
