Lead oxide, which is used to create the paste used on the battery plates, is either produced by the Ball Mill Process or the Barton-Like Process.It may also be purchased from an oxide producer (see receiving). The major source of lead exposure in the oxide production process comes from leaking equipment and system upsets.

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
With more than 100 years of experience in ball mill technology, 's ball mills are designed for long life and minimum maintenance. They grind ores and other materials typically to 35 mesh or finer in a variety of applications, both in open or closed circuits.

potential ability of the process engineers to control processing parameters to accomplish the desired cement fineness levels. In the second part of the study, a quantitative procedure for monitoring and evaluating cement milling process performance was described. Some control charts
Advanced process controls. Our state-of-the-art grinding process control solutions make it possible to stabilize, adjust, and improve your grinding results. These enhancing technologies accompany our grinding mills and make the grinding process more efficient, which adds significant value to the whole concentration process.
That does not mean that the preference is speed control over feed rate control. Each ore is different and each plant is different. As equipment designers, we have to provide each of the features that the operators could use to optimize their process. In my experience, SAG Mills are normally variable speed, and Ball Mills are normally fixed speed.
Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact, ball milling process is not new and dates back to more than 150 years.
