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 ...

Ball mass is an important parameter that is known to have an influence on the outcome of a mechanochemical reaction induced by ballmilling. A standard way of modifying the ball mass is to change the size of the ball made of the same material.

If you have never seen a ball mill full of black powder or whistle mix explode, you have missed one of life's truly sobering experiences. If you are milling an explosive mix, use lead or brass media. If you are milling a single chemical (not a mix) that is not likely to explode or ignite, you can use ceramic. I'll look around for brass.
