The two types of mills work very differently. NEVER mill mixed chemicals together in a blade mill. Its violently spinning, hard steel blades will likely cause mixed black powder chemicals to ignite or explode. But in a ball mill the relatively gentle tumbling action of mixed black powder chemicals and lead balls is far less dangerous.

A ball mill is a rotating drum with dozens of lead balls inside. The 3 chemicals are loaded into the ball mill, along with the lead balls, sealed shut and allowed to rotate for anywhere between 1 and 24 hours.

The balls really don't need a break in but have found small pieces of lead during fresh media break ins. The mold seam lines are smoothed also.

I was using a 4" PVC waterpipe with endcaps, filled with 200 musket balls out of lead. The balls are 11,65mm in diameter. One endcap is filled with lead balls, but I really doubt that this is enough.

It was milled for six hours. Although neither where clumping to badly the sides of the drum with the nickels where cleaner than the lead ball media drum.

where d b.max is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the …

Just load the barrel with it's load weight of lead balls (it will not look full!) and add a little material to mill. From experience a cheap rock tumbler is cheaper than a DIY ball mill. BUT you can make the mill to suit your needs, if you have the skill tools and time.

(I don't use the small rubber chambers for brass cleaning as I built a larger chamber from 4" PVC that holds more and is easier to seal and open.)

Are those large enough for effective ball milling?
