Granular flow and segregation in a four-bladed mixer

Segregation measurement of powder injection molding feedstock using thermogravimetric analysis, pycnometer density and differential scanning calorimetry techniques

“…Particle segregation of dry powder particles has been studied by die filling, shear blender, rotating blender, vibrated shaker, Hele Shaw cells and fluidized beds using measurement techniques such as optical techniques, particle image velocimetry, radioactive particle tracking and infrared or near-infrared spectroscopy [5][6][7][8][9][10][11][12][13][14]. It is well accepted that size and density are the two main factors responsible for particle segregation.…”

A method for characterising solids translational and rotational motions using Multiple-Positron Emission Particle Tracking (Multiple-PEPT)

“…Characterisation of solids motion has been studied in a variety of systems, for instance, visualization of circulating fluidized beds (Horio and Kuroki, 1994); mixing studies in drums (Santomaso et al, 2004(Santomaso et al, , 2005, granular flow and segregation in four-bladed mixer by Conway et al (2005); and solids motion studies in fluidized beds by Gera et al (1998) and Werther (1999). All these focus on the translational motion of the solids alone.…”

Mixing of particles and powders: Where next?

“…Mechanically stirred vessels have been studied e.g. Stewart, Bridgwater, Zhou, and Yu (2001) and Conway, Lekhal, Khinast, and Glasser (2005). With regard to measurement, some on-line monitoring by e.g.…”
