Batchwise or continuously operating mixing kneader for treatment of products, which comprises:
- a circular-cylindrical housing having housing walls and a longitudinal axis;
- a kneading shaft mounted in said housing and running coaxial to the housing axis;
- disk elements mounted on said shaft perpendicular thereto, said disk elements having an outer diameter;
- co-rotating kneading bars fixed on said outer diameter including arms arranged adjacent said housing walls and at least one radial element fixed to said arms and extending towards the kneading shaft, wherein said disk elements and kneading bars form a plurality of radially co-rotating shearing gaps;
- and radial carrier arms fixed in the housing wall, support arms carried by said radial carrier arms and running axially along said kneading shaft, and fixed kneading counterelements carried by said support arms and engaging said shearing gaps.
