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 paintsBall 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 steel ballsThe mass ratio of air to coal is dependent on the coal mill manufacturer and usually ranges from 175 to 22 with a typical value of 20 An air to fuel mass ratio of 18 produces a primary stoichiometric ratio of approximately 016, or 16% of the air necessary for complete combustion of the coalCoal Mill an overview | ScienceDirect Topics
