08/05/2019· Using water as a grinding medium enabled viscosity changes during the mechanochemical process in a ball mill, (Orumwense and Forssberg 1992). This effect can significantly influence the efficiency of the MCA. Diluted suspension can hinder the movement of the balls and thus decrease the impact forces transmitted to the processed material. On the other hand, an insufficient14/06/2017· Investigation of the parameters of the ball-milling synthesis revealed that the degree of lactide ring-opening polymerization could be modulated by the ball-milling time, vibration frequency, mass of the ball media, and liquid-assisted grinding. Liquid-assisted grinding was found to be an especially important factor for achieving a high degree of mechanochemical polymerization.
