(A) Optimization of the mechanoredox arylation and borylation reactions. (B) Reaction mixture of the mechanoredox arylation of 2a after grinding in a ball mill. A stainless steel milling jar (1.5 ml) and a stainless steel ball (diameter, 5 mm) were used. See supplementary materials for details. equiv, equivalent; h, hour.
The results on optimization of reaction conditions in the ball mill indicate that FC acylation could be effectively carried out mechanochemically. The best mechanochemical reaction conditions (Table 1, entry 4): 2 h, equimolar amount of phthalic anhydride and 2.5 equivalents of AlCl 3, afforded product 3 in high yield (79%).

The present invention is directed toward a material handling, processing and milling facility which utilizes ball milling as a means for material grinding, mixing or mechanical alloying of materials. The system includes an automatic ball charging, agitating and indexing assembly, constructed and arranged to deagglomerate and directly distribute a plurality of grinding balls to the facility.
The optimization of ball milling process may be one of the key process parameters to achieve the high-ZT thermoelectric Bi–Te-based compounds. The ball milling process involves many parameters such as milling time, ball-to-material weight ratio, grinding ball size, milling speed.
Ball milling of rye bran gave rise to similar results, with the A/X ratio of the extractable AX being considerably lower (0.51). Optimization of the ball mill treatment by varying the degree of filling of the milling jar permitted us to obtain equally high WE-AX levels (>70%) in wheat and rye bran within a 24 h ball-milling period.
Optimization of mill performance by using online ball and pulp measurements In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product becomes coarser again. At this level, a drop in grinding efficiency occurs. (Figure 7.)
