Sep 15 2011 1 introduction due to their high energy density planetary ball mills are especially suited for fine and ultrafine grinding of hard and brittle material down to the nanometre size range for mechanical alloying and for mechanochemical reactions among others in comparison to ball mills and vibrating mills higher stress intensities can be generated due to the centrifugal field
Hi observing high vibs on pressing and lifting pinion de and nde bearing on a ball mill motor and main gb drive are ok clear predominant gear mesh frequency is appearing in the spectrum along with harmonics and side bands but 1st gmf is predominant side bands with pinion speed is seen no gg speed side band was observed some of the vib data spectrums and photos shown in the attachment
Sep 01 2004 a 14ball end mill is a small tool and holder assembly which in turn has a low mass so it will have a higher natural frequency reading than a oneinch ball end mill assembly therefore it is likely that this 14ball end mill assembly in this machine will want to run much faster of an rpm to stay out of chatter than this machine can give

If a ball mill uses little or no water during grinding it is a dry mill if a ball mill uses water during grinding it is a wet mill a typical ball mill will have a drum length that is 1 or 15 times the drum diameter ball mills with a drum length to diameter ratio greater than 15 are referred to as tube mills
These mills are characterized by their large diameter and short length as compared to ball mills the inside of the mill is lined with lifting plates to lift the material inside the mill where it then falls off the plates onto the rest of the ore monitoring of this type of equipment is crucial for modern mining operations
