Sep 17, 2019· For one thing, smaller diameter media are more expensive per unit weight. As the ore becomes larger and harder, the media need to be of a larger diameter to grind. Also, the smaller the media, the sooner it reaches reject size. This is especially true in the case of a rod mill where rods break up below 1 to 1 ½ in diameter.

As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
