    Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90 of the critical speed. Six lifter bars of rectangular crosssection were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4. As can be seen from the

  • Ball Mill Wikipedia
    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 pebbles

    Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50 solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6 moisture. As such, when the product is sticky, rod mills are preferred over ball mills.
