WhatsApp: +86 18203695377For 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.
WhatsApp: +86 18203695377Planetary ball mills are used for the pulverization of soft, hard, brittle, and fibrous materials in dry and wet mode. Extremely high centrifugal forces result in very high pulverization energy and therefore short processing times. Planetary ball mills are ideally suited for tasks in research like mechanochemistry (mechanosynthesis, mechanical ...
