Ball mill - Wikipedia

OverviewDescriptionWorkingAppli ionsAdvantages of the ball millVarietiesSee alsoA ball mill, a type of grinder, is a cylindrical device used in grinding or mixing materials like ores, chemicals, ceramic 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…Wikipedia & 183; CC-BY-SA 许可下的文字
