ادامه مطلبA 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 steel balls.
ادامه مطلبLike other ball mills, planetary ball mills provide a slight advantage in metal-free grinding, because an operator only needs to line the tank and use ceramic media to achieve a metal-free environment (as opposed to internally agitated ball mills, which require the arms and shaft to be sheathed, which is easily done).
ادامه مطلبThe wear rate of the grinding media ball can be calculated with the help of the formula R=KW=Kπ /6SD³. The manufacturers use this formula to know the exact value of the grinding media ball's wear rate. In this grinding media ball formula, S is known as the weight of the material that is used in the manufacturing of the media balls.
