Particles move along arcs of circle of different radius in the passive zone, and flow parallel to the free surface in the active zone (see Fig. 1).All the trajectories are concentrically organized, and there is a stagnation point at the bottom of the free flowing zone.

Liquid induced cohesion has a significant effect on the flow characteristics of wet granular assemblies. The strength of capillary forces between the particles can be continuously tuned by making the glass beads hydrophobic via chemical silanization. Main results of rotating drum experiments are that stronger liquid-induced cohesion decreases the width of the flowing region, the velocity of ...

Drag, diffusion and segregation in inertial granular flows

Key words: granular mixing, dry granular material, avalanches 1. Introduction Granular segregation occurs routinely whenever a mixture of non-identical grains is sheared. This segregation generates a small relative motion between grains of different size, density or shape, which over time causes demixing and a spatially inhomogeneous ...

Feb 04, 2013  Highlights Transverse mixing of wet particles in rotating drums is investigated. Interparticle cohesion in general reduces mixing performance. Dry particles have the poorest mixing performance at 64% filling level. Particle mixing is affected by particle circulation period and its variance. A mathematical model is developed to predict mixing performance.

Granulation - Wikipedia

Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular material.It is applied in several technological processes in the chemical and pharmaceutical industries. Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between 0.2 and 4.0 mm depending on their subsequent use.
