摘要
Talc powder samples were ground by three types of ball mill with different sample loadings, W. to investigate rate constants or the size reduction and structural change into the amorphous state. Ball mill simulation based on the particle element method was performed to calculate the impact energy of the balls. E-i,E- during grinding. Each rate constant correlated with the specific impact energy defined by E-i/W on logarithmic coordinates with a high correlation factor.
