Dec 10, 2013 X-ray diffraction line profile analyses were used for determination of the dislocation structure of ball-milled copper and iron samples. Plots of integral breadths of the diffraction line profiles in accordance with the classical Williamson-Hall equation clarified stronger strain anisotropy in iron than copper. By the analyses of the integral breadths in accordance with the modified Williamson ...
A study has been made of the effect of fine structure on the decrystallization process which results from the ballmilling of cellulose. The rate of decrystallization is sensitive to the type of fine structure and is accelerated by the presence of moisture.
This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types grid type ball mill and overflow type ball mill.
