Mechanochemical Cross-Coupling Reactions
The working mechanism is described in this section. Ball-milling uses one type of grinder that consists of a grinding jar filled with rigid balls (stainless steel balls, zirconia balls, etc.), such as mix mill, planetary mill and rolling mill [45] (Fig. 2a). Depending on the type of movement, different forces are applied.

Grinding Media in Ball Mills-A Review
According to Swart et al. [9], ball mills are mostly used because of their very high size reduction ratio, although they have a very low energy efficiency of about 20%. According to Conger et al. [10], many factors affecting ball mill effi-ciency include mill design, liner design, mill speed, charge ratio, and grinding media properties.

For milling speed, since previous works usually used high speed ball milling which is more than 100 rpm, the best speed for low speed ball mill is unknown. Since higher speed results in higher collision between grinding balls and powder [ 7 ], the three highest speeds of the ball mill will be used which are 100 rpm, 95 rpm, and 90 rpm.
