QM series planetary ball mill has four ball milling tanks on a big tray, and when this big tray circumvolve (revolution), it will drive ball milling tanks to circumvolve (rotation) surrounding its rotor axis to form epicyclic motion. The drive ratio of revolution and rotation is 1:2 (one circle of revolution will make two circles of rotation).
