Ball mill - Wikipedia
Ball Mill - Wikipedia

critical speed can be understood as that speed after which the steel balls that are responsible for the grinding of particles start rotating along the direction of the cylindrical device, thus causing no further grinding. ball mills are used extensively in the mechanical alloying process in which they are used for grinding and for cold welding, producing alloys from powders.
