Abstract

See full text

An apparatus having a cylindrical structure which has therein a rotary shaft extending along the axis of the cylindrical structure to project beyond the lengthwise end portions thereof, and a plurality of dispersion chambers and an arbitrary number of rectifying chambers arranged along the rotary shaft can be used for continuous dispersing in the manufacture of several products. Each of the dispersion chambers and rectifying chambers consists of a space defined by the circumferential surface of the rotary shaft and between adjacent distance collars. Each of the distance collars is fixed at its outer circumferential surface to the inner surface of the cylindrical structure, and forms at a part of its inner circumferential surface in cooperation with the circumferential surface of the rotary shaft an annular slit which constitutes a passage for a material current. The dispersion chamber houses in the inner space thereof a rotary blade having a shearing edge, and fixed to the rotary shaft so that the rotary blade extends at right angles to the longitudinal direction of the rotary shaft. The rectifying chamber houses in the inner space thereof a bearing for the rotary shaft, which is fixed to the inner surface of the cylindrical structure and provided with a plurality of small gaps which constitute passages for the material current.
