The grinding efficiency depends on factors such as size, density, and the number of the balls in the mill. The bigger and denser the balls are, the more the energy input will be, and it will lead to quicker grinding. However, employing balls that are way too large might result in a less grind and increased wear of the mill's inner lining.
