where d 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 mill and milling efficiency.

Q: Can I use alumina or ceramic balls in my ball mill for making black powder and whistle mix? A: Sure. Once. Alumina or ceramic milling media make little teeny tiny sparks. Sparks are what we use to ignite flammable and explosive mixes with. So, the odds are pretty high that using them to grind explosive mixtures will result in an explosion.

A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.
