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 pebbles2023年4月4日· Grinding iron ores in conventional ball mills involve a considerably high consumption of metallic media, resulting in high operating costs In the case of compact itabirites, the high silica content increases such consumption, potentially exceeding the costs associated with electric power consumption in industrial operations This paper presentsStudy on Partial Replacement of Metal Grinding Ball with Pebbles
