Apr 26, 2021 The introduction of the ball mill instrument realized the automation of the first step of matrix solid‐phase dispersion. Several extraction parameters were evaluated, and the best extraction conditions were optimized by response surface methodology. The method exhibited a good linearity for the five compounds (r 2 0.999).
Mar 13, 2021 An efficient and rapid ball mill‐assisted vortex‐enhanced matrix solid‐phase dispersion method was developed for the simultaneous quantification of five phenols (ellagic acid, kaempferol‐3‐O‐rutinoside, astragalin, tiliroside, and kaempferol) in Rubi Fructus by high‐performance liquid chromatography. The introduction of the ball mill instrument realized the automation of the first.
Design Method of Ball Mill by Discrete Element Method The grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the spe-cific impact energy of the balls calculated from Discrete Element Method simulation. This relationship was successfully used for the scale-up of a rocking ball mill, and the optimum.
