A general calculation method is presented in https://doi.org/10.1002/anie.202409731 for traversing synthetic protocols derived from mixer or planetary ball mills; finding (1) the point impact energy Eimpact of a single collision between the ball and the molecules, and (2) the cumulative energy Etotal, which is transferred to the reaction mixture during the whole milling process. Similarly, experimentally relevant parameters such as RPM and time can be determined when the cumulative energy Etotal is known.
##Button description##
Eimpact and Etotal in planetary ball mills can be calculated based on known parameters: Effective diameter of milling disk, diameter of the jar, the height of the jar, the diameter of the ball, the mass of the ball, the total number of balls, RPM, and milling time.
Add #: Number of calculations added to the data table.
For “theory to practice”, the commercially available mill is taken to simulate kinematics of a one-dimension mill. Eimpact and cumulative energy Etotal are calculated based on known parameters: Diameter of the jar, length of the jar, amplitude of the jar, diameter of the ball, mass of the ball, total number of balls, frequency, and time. If the “Amplitude of jar oscillation” is unknown, the use of an ideal amplitude equal to half the length of the jar (A = lj/2) is recommended.
