  • Mill Charge an overview | ScienceDirect Topics

    Based on their results, [42] it is concluded that the rate of amorphization depends strongly on the kinetic energy of the ball mill charge and this depends on the number of opportunities for the powder particles to be reacted and interdiffused. Increasing the W b:W p ratio accelerates the rate of amorphization, which is explained by the increase in the kinetic energy of the ball mill charge ...
