  • high energy ball milling in brazilME Mining Machinery

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