The improved robustness of air sensitive reaction processes is an emerging theme for reactions which can benefit from being conducted in a ball-mill. Indeed, the mechanochemical ball-milled versions of palladium catalysed cross-couplings such as the Buchwald-Hartwig reaction, thiol aryl/alkyl-ation and palladocycle formation have all been ...

If the ball mill will always operate at a fixed speed, the VSD is an expensive option. One major disadvantage of using a VSD or a fuid coupling, is that there is an additional 5% loss all the time that the ball mill is operating. The soft starter has only about 0.5% loss and a much longer expected life. Best regards,
