    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 a planetary ball mill result in very high pulverization energy and.2 Selection by required particle size The steel ball of ball mill and the mineral material are in point contact so the finished product has a high degree of fineness but it is also prone to over grinding Therefore it is suitable for the production with high material fineness and is not suitable for the gravity beneficiation of metal ores.
