In order to investigate the axial segregation profile of binary solid mixtures during the mixing and segregation processes in a horizontal rotating conical vessel, experiments were carried out by using several kinds of binary mixtures, such as alumina/silica sand mixture and different size silica sand mixtures, as materials. The axial concentration distribution of the mixtures was measured at a different mixing time under three different initial loading conditions at the rotating speed of the vessel n=10-30 rpm. It was confirmed that the demixing potential φ, proposed in the Rose's Equation, was correlated with the concentration C^^-_A of the specified particles within a specified zone of the vessel, which was itself closely related to the axial arrangement of the particles in the vessel, regardless of the mixture or dimension of the vessel. With the aid of this relationship between φ and C^^-_A, it was possible to estimate the axial concentration distribution of a mixture in the vessel.
