Ball mill by rpm nnd hz

Jul 08, 2008 Or you could just buy a European mill or a usa mill with a motor capable of handling 220V @ 50 Hz. You need more then a transformer by the way. The frequency is 20% higher in the usa. So the rpm of your milling jar will be lower than the designed rpm. I'm sure a euro can supply you with a ballmill, or can assist you to make one
