ABSTRACT:
A continuous kneader comprising a rotary screw shaft and rotatable within a cylinder for transporting a fluid axially thereof, rotary disks mounted on the shaft and each formed on each side surface thereof with radial projections and recesses arranged alternately, and fixed disks provided on the cylinder and arranged on the opposite sides of each rotary disk coaxially therewith as opposed thereto. Each of the fixed disks is formed on each side surface thereof with radial projections and recesses arranged alternately. The boundary between and defining each projection and the recess adjacent thereto on at least one of the rotary disk and the fixed disk is inclined from the radial direction so that the material supplied from a space between the shaft and the inner surface of the cylinder to the space between the rotary disk and the fixed disk is passed over the rotary disk outer periphery toward the axis of the shaft into the space between the rotary disk and the fixed disk immediately adjacent thereto. The projections and the recesses are so formed as to reduce the space between each rotary disk and the immediately adjacent fixed disk from disk to disk toward the forward end of the cylinder. The apparatus assures an efficient kneading operation although having a compact construction.
