  • High Energy Ball Milling an overview ScienceDirect Topics

    High energy ball milling is a ball milling process in which a powder mixture placed in a ball mill is subjected to high energy collisions from the balls. High energy ball milling, also called mechanical alloying, can successfully produce fine, uniform dispersions of oxide particles in nickel base super alloys that cannot be made by conventional powder metallurgy methods.

    This size should be the largest ball size charged to the mill. The second objective is to provide the correct ball size distribution to grind the finer particles in the composite ball mill feed. This objective may necessitate charging a second, smaller ball size with the maximum ball size. The practice of charging a pre determined ratio of two or more ball sizes to a mill is called rationed ball charging.
