Now a volume of green meal equal to 25% of the mill jar volume is measured. For this jar, that volume is 3 and 1/4 cups of our bulk green meal. This is the first approximation to the theoretically ideal mill jar charge. It is added to the jar along with hardened lead milling media equal to 1/2 of the mill jar volume.

Ball Milling Glazes, Bodies, Engobes

If you are using a ball mill in your operation resist the temptation to think that using one is just a matter of throwing in some pebbles, pouring in the glaze, and turning it on for an hour or so. As a general rule you should mill for the same amount of time, fill the jar to the same level, use the same charge of pebbles and the range of sizes of the pebbles should be controlled (the pebbles

Optimization of mill performance by using

mill absorbed power and ball filling degree. As indicated on the graph, a small variation in power could be the result of a significant variation of balls filling degree. 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

Powder metallurgy – basics applications

The ball to charge ratio may be 5:1, 10:1, 15:1. This method is more efficient in achieving fine particle size. Rod mills: Horizontal rods are used instead of balls to grind.
