ABSTRACT:
A continuous kneader includes a screw shaft rotatable within a cylinder, and rotatable disks fixedly mounted on the shaft for rotation therewith. Stationary disks are arranged in face-to-face opposed relation to the rotatable disks. Each of the opposed surfaces of the disks is formed with alternating ridges and furrows. The material is passed between the opposed disk surfaces while being subjected alternately to compressive and shearing forces. Grooves are formed in the inner peripheral surface of the stationary disk and a screw section is carried on the adjacent outer peripheral surface of the drive shaft to promote the axial advance of the material through the device.
