The size of the grinding balls in a ball mill significantly influences milling performance, affecting both efficiency and product quality. Smaller balls are more effective for grinding fine particles due to their higher surface area-to-volume ratio, which enhances the frequency of collisions and grinding action. Conversely, larger balls are better suited for grinding coarse particles because
