Recognize important considerations in ball mill selection. Reading & Lecture. In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill.

To load the mill jar optimally, fill it half full of a dense media such as 1/2-inch lead balls. 50-caliber muzzle loading bullets will work, but they are soft and will both wear down over time and leave lead dust in whatever it is you are milling. It''s better to antimony-hardened 1/2-inch diameter lead balls, made specifically for pyrotechnic ball milling. They cost a little more than the soft

The distance to the level ball charge from the inside top of the mill must be found, and the average diameter and length of the compartment known. A chart such as depicted in figure 1 can be made to relate depth to percent filling, or the weight of the ball charge. Subtraction of this weight from the previous known (or calculated) weight yields the loss in the compartment due to wear. Applying
