Quantitative assessment of the refined theory of motion of balls in a ball mill

Abstract

The refined theory of the motion of the outer row of balls in a ball mill takes into account the relative motion of the uppper ball to the lower ball, which is at relative rest with respect to the drum. To determine this relative motion of the refinement, the theory gives two differential equations (see article). This work is devoted to a quantitative assessment of the new theory. The author of the article studies the movement of the outer row of balls in a ball mill, observing the movement of the upper ball relative to the movement of the lower ball. Each specific numerical example is the moment when the upper ball separates from the lower ball.
