In order to investigate the axial segregation characteristics of binary solid mixture in a horizontal rotating conical vessel, experiments were carried out by using binary mixtures of particles having various sizes, densities and shapes.
On a basis of the assumption that the axial segregation in a conical vessel is controlled by two factors; one is the radial segregation of binary mixture in the vessel and the other is the cascading angle difference between particles of the mixture, each of these factors was measured in a horizontal rotating cylinder.
As a result, it was obtained that the final axial segregation can be estimated by the segregation characteristics given by the above factors.
