What are these? Cannon balls? Ball bearing blanks?

I found these in an old garage.
Not sure what they are. Does anyone have know or a good guess?
They are about 4-1/4 inches in diameter and has a ridge about 1-1/2 inch wide and protrudes about 1/8 inch.

Those were the prototypes God used when forging my nuts.

Careful you don’t try to lift them. You’ll hurt your back.

I fabbed up a leg cuff , welded a length of chain to it, then welded that to one of those crusher balls. It was a great conversation piece with the strippers at his bachelor party.
Even better when we had to zipcut the whole mess off his ankle the next day.

I agree with Snurge. They are balls for a Ball Mill, used for crushing ore.

Third vote for ball mill ore crushers. I've got half a dozen of them (impossible to drill btw) about two inch in diameter. I used to spend days drilling the end caps for the mills themselves: 40 foot cast iron pie plates, 2 1/4" holes. Many Many holes.
 
Yup, mine crusher balls, I have a pail of the 1.5" ones that I do use in my small cannon, they work excellent and if you can find them afterwards are completely re-usable

The 1.5 " balls weight 15 oz. and I have crono'd them at 1375 fps...they hit hard, will put a 1/2 size of the ball dent in 1/2 steel at 100'.

Wish I had a pail of them for the "big gun"...2.625 Dia bore.
