Optimum Ball Mill Size (3 replies)

Hi all,

I am looking at purchasing a new ball mill for a slice sand operations. We are looking to grind down a 170/270 whole grain silica to a 325 Mesh (-200). I'm beginning this search and would like any opinions on what size of ball mill to explore for taking such a fine whole grain and pulverizing finer.


Thanks for any help.

Hello!  If you look on https://www.911metallurgist.com/blog/eq at # 9 and 10 are the ball sizing formulas.

If you want to size a ball mill, you need use formula 15, 16, and 17

You also need to know what capacity/tonnage/volume you want to process.
