Granular segregation in the double-cone blender ...

Feb 15, 2001  We investigate granular segregation in one of the most common industrial devices used in granular processing: the double-cone blender. We report several new and spontaneously occurring segregation patterns, including stripes, bands, and a symmetry-breaking state in which one species vacates half the tumbler. By varying the tumbling speed along with particle size and size ratio, we find

Magnetic Resonance Imaging (MRI) was used to study the mixing process of binary mixtures of free flowing sugar beads in a Turbula mixer. In order to make particles MRI-sensitive, some reference beads were doped with an organic oil. Doped and undoped particles were mixed and MRI was used to non-destructively image the particle bed for a given number of mixer rotations (NR), bead diameter ratio ...
