Ball size. All balls should be the same size. To allow a stable cascade, ball diameter should not be much larger than 20% of the jar diameter. Smaller balls have more surface area and will have more strikes per revolution allowing for faster milling, but each strike has less energy, reducing effectiveness against harder materials. Larger balls ...
