The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

A ball nut with all the backlash removed is called preloaded. There are several ways to reduce or eliminate the backlash in a ball screw assembly: At the factory level we can select ball sizes to minimize the backlash. This works well for small lead to diameter ratios, like a 5x25mm. In some cases we can preload a ball nut in this way.

In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."

1. Move an axis in one direction farther than the maximum possible backlash. (Example .020, hopefully less than that is needed!) 2. Mount a dial indicator and zero it. 3. Move the axis again in the same direction for a specific distance (it doesn't matter how far). 4. Move the axis backwards the same distance.
