WhatsApp: +86 18838072829Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or largescale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.
WhatsApp: +86 18838072829A 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 ...
WhatsApp: +86 18838072829Ball mill, also known as tumbling or pebble mill is milling equipment that encompasses cylindercontaining balls and is mounted on a metallic frame that can be rotated along with a longitudinal axis. The large ball tends to break down coarse feed materials and the small ball mill to form fine products by reducing void spaces.
