High energy ball milling

Apr 22, 2021

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

    High Energy Ball Milling. In discussions on high energy ball milling, the more generic term “ball mills” is often used in place of the terms “stirred ball mills” or “Attritors,” but the differences between the types of mills are quite distinct. And, depending on your application, you may find that one type of high energy ball milling is more appropriate for your operation than another

    The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming effects. These ball mills are also suitable for mechano chemistry
