For Ball milling and most other applications, the ratio between the speed of the sun wheel and the speed of the grinding jar is 1: 2. This means that during one rotation of the sun wheel, the grinding jar rotates twice in the opposite direction. This speed ratio is very common for Planetary Ball Mills in general.
