Planetary Ball Mill PM 400

Description

Planetary Ball Mills are used wherever the highest degree of fineness is required. Apart 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 processes. The extremely high centrifugal forces of planetary ball mills result in very high pulverization energy and therefore short grinding times.
