In order to investigate the effect of particle-permeation on the segregation of solid mixture in a rotating vessel, radial and axial segregations of spherical binary solid mixture were observed by using a horizontal rotating cylinder and a horizontal rotating conical vessel. The binary mixture used was made by combining glass beads, spherical alumina particles and spherical silica-gel particles having various sizes and densities. As a result, it was obtained that radial and axial segregations of binary solid mixture in a rotating vessel were closely related to the permeation effect (x_T/x_B) measured in a moving bed. On the basis of the permeation effect (x_T/x_B), it was tried to estimate the segregation pattern, degree and direction of the mixture cascading in a vessel rotated at lower speed of rotation.
