湿式媒体撹拌ミルによるカオリナイトの粉砕

抄録

The pulverization condition was examined for pulverizing of kaolinite by a beads agitating attrition mill without peptizer. Georgia kaolinite was pulverized with the individually varied conditions of pulverization period, concentration of the slurry, and rotation speed of the agitation rod. The measurement of particle size distribution, observation by transmission electron microscope, and estimation of crystal size in the 001 direction from X-ray diffraction data were carried out to check the degree of the pulverization. The damage of kaolinite and contamination from the mill were also monitored. Kaolinite could be pulverized with the slight damage and contamination under the condition of higher concentration of the slurry, slower rotation speed of the agitation rod, and shorter pulverization period.
