One of the few things I had to buy for this project, aside from the casters, was the steel balls. I found these online. They were quite inexpensive. I went with 5/8 inch diameter balls, which seem to work well in a mill this size. I have been powering the ball mill with my bench variable power supply so I could fine tune the rotation speed.
This article on choosing milling media for a ball mill by Ned Gorski is a side article that goes with the "Ball Milling 101" article.Milling Media Cautions. In his book Ball Milling Theory and Practice for the Amateur Pyrotechnician, Lloyd includes a section on casting your own lead media.
[citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter.
They used a small homemade ball mill composed of a stainless steel container with a diameter and height of 8 and 12 cm, respectively, and 400 small stainless steel balls in two different sizes of 0.6 and 0.8 mm. The study of rheological properties of nanocomposites showed that the simultaneous milling of the latex and CNTs can lead to ...

Apr 26, 2019· 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.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
