Planetary ball mill is a very often used machine for mechanical alloying, especially in Europe Because very small amount of powder (for example, as little as a few grammes), is required, the machine is suitable for research purposes in the laboratoryNote that the models proposed earlier for mechanical alloying in planetary mill [23, 24] ignored rolling ball motion as affecting the refinement or phase changes in the powder being processed In Physics of Mechanical Alloying in Planetary Ball Mill and Planetary Ball Mills are used wherever the highest degree of fineness is requiredApart from the classical mixing and size reduction processes, the mills also meet all the technical requirements for colloidal grinding and have the energy input necessary for mechanical alloying processesThe extremely high centrifugal forces of planetary ball mills result in very high pulverization energy and Planetary Ball Mill PM 400 RETSCH powerful and quick
