Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steelballs. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other e

How I built a quick and easy home-made ball mill

It doesn't look like much, but it works great, and it cost almost nothing to build. As a bonus, this ball mill can also be used as a rock tumbler, or a glass tumbler to make your own "sea glass" at home. To use the mill as a rock tumbler, just leave out the steel balls, add rocks, tumbling grit and water, and let it spin.

Ball Mill: Operating principles, components, Uses ...

11-01-2016  The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.

Steel mill - Wikipedia

History. Since the invention of the Bessemer process, steel mills have replaced ironworks, based on puddling or fining methods. New ways to produce steel appeared later: from scrap melted in an electric arc furnace and, more recently, from direct reduced iron processes.. In the late 19th and early 20th centuries the world's largest steel mill was the Barrow Hematite Steel Company steelworks ...
