Abstract:
1. A mixing and kneading machine particularly for compounding bulk-flowable, plastic and/or pasty masses comprising: a working space enclosed by a casing; a plurality of kneader pins secured to the casing and protruding into the working space, each of said kneader pins having a pin main surface; and a working member disposed within said casing for rotation and translation within said working space, said working member provided with a plurality of kneader vanes each having a vane main surface facing a pin main surface to define a gap therebetween to impart a shear deformation force to the mass flowing through said gap as said working member rotates and translates, wherein said vane main surface of at least one of said plurality of kneader vanes is substantially non-linear in the radial direction along substantially the entire height of the vane main surface from an outer diameter of the kneader vane toward a base diameter of the kneader vane to control the shear deformation of the mass.
