ball milling basics

Forball milling, there is an optimum speed where the centrifugal force at the top of themillis just balanced by the force of gravity. This caused the balls to be lifted to the maximum height before they fall onto the balls below, thus imparting the most kinetic energy. Inpractice, theball millis run at just below this speed (70–80%).

Ball Milling- an overview | ScienceDirect Topics

Ball millingis a grinding method that grinds nanotubes into extremely fine powders. During theball millingprocess, the collision between the tiny rigid balls in a concealed container will generate localized high pressure. Usually, ceramic, flint pebbles and stainless steel are used.25 In order to further improve the quality of dispersion and ...
