We did several shear experiments using a rotary shear apparatus with the shear displacement ranges between10mm to 1m. As an automated particle image analysis, Morphologi G3-SE (Malvern Instruments) was used for evaluation of particle size and shape. The observation mode was diascopic mode (Transmittance mode) and a magnification was choose to sufficient to cover 1 to 1,000um. The sample was dispersed with SDU (Sample Dispersion Unit) which attached Morphologi G3-SE. Number of measured particles was over than ten thousand and a parameter filter function on software was used based on shape and pixel number of particle image. We also used a laser diffraction instruments with dry dispersion methods, Mastersizer3000 with Aero unit (Malvern
Instruments) for evaluation of particle size in less than 1um as fine particles.
