  • Ball mill simulation in wet grinding using a tumbling mill

    Jun 25, 20040183;32;One of the most popular ball mills is a tumbling ball mill which consists of a rotating cylindrical drum (with lids) with grinding media such as balls. The grinding performance is related to the ball motion in a drum (pot) during milling and is dependent on operational conditions such as rotational speed, ball filling, mill size and sample charge.

    For ball milling, there is an optimum speed where the centrifugal force at the top of the mill is just balanced by the force of gravity. This caused the balls to be lifted to the maximum height before they fall onto the balls below, thus imparting the most kinetic energy. In practice, the ball mill is run at just below this speed (7080%).
