Rod Mill - an overview ScienceDirect Topics

In Mineral Processing Design and Operations (Second Edition), 2016. 8.3.1 Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.

2020-11-12  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.
