Potential and kinetic energy of waterpower was important to operation of the mills in Lowell. At its most basic, the height of water is crucial to creating waterpower. Friction, turbulence, and other factors reduced the actual energy in the mills. "Conservation of Energy" concepts are also evident in the "loss" of energy in the

Todays ball mills are typically designed to operate with ball charge fillings up to 35% by volume. There are cases where this figure is higher, for example with mill shells designed for higher loadings, but these cases are becoming more rare, with the additional cost of steel becoming prohibitory of this design.
