Measuring high voltage or the "static electricity" on your

Spark Length. To measure high voltage, attach two large and polished brass balls (2" dia. or larger) to an insulating plate so there is a 1/2 millimeter gap between them. You can verify the 2,800-volt breakdown voltage of this spark gap by using a high-voltage DC power supply to produce sparks between the balls.

Addition of pebbles to a ball-mill to improve grinding

It was therefore decided to use a charge volume of 33%, which is within the typical charge volume range of 30% to 35% for large diameter overflow ball-mills (Kawatra, 2006). Mulenga and Moys (2014) found that the rate of production of fines was optimized when the voids within the static charge were filled completely and no slurry pool was visible.
