Processes inside planetary ball mills are complex and strongly depend on the processed material and synthesis and, thus, the optimum milling conditions have to be assessed for each individual system. The present review focuses on the insight into several parameters like properties of grinding balls, the filling ratio or revolution speed.
During the last decade numerous protocols have been published using the method of ball milling for synthesis all over the field of organic chemistry. However, compared to other methods leaving their marks on the road to sustainable synthesis ( microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemists.
The most used milling types are shaker and planetary mills. The shaker mills are applied to small samples, while planetary mills are used on the industrial scale for sample processing and colloidal grinding.

The grinding process in the ball mill is due to the centrifugal force induced by the mill on the balls. This force depends on the weight of the balls and the ball mill rotational speed. At low speeds, the balls are at a fall state (Figure 9(a)). As the operating speed increases, the balls reach a higher helix angle before falling and repeating ...
