Abstract
A mixer,comprises a disc,having peripheral edge,, which is formed in a circular profile concentric with inner circumferential surface,of annular outer wall,lower pins,provided with rear bulged portions,extend backward of the rotational direction R; and upper pins,provided with front bulged portion,′ which extends forward of the rotational direction. A disc without a toothed formation on its peripheral edge zone can prevent the slurry from depositing on the outer periphery of the disc. Front and rear bulged portions,occupy a rearward area of the lower pin and a forward area of the upper pin so as not to provide retentive regions for the slurry, which might otherwise have caused a vortex or turbulent flow of the slurry. Accordingly, the deposition of slurry on the lower and upper pins can be prevented from occurring.
