High hardness materi-als become very abrasive therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding action is caused mainly by particle-particle collisions, so wear to the mill’s internals is less of an issue.

    GUI The PM 100 planetary ball mill is a benchtop unit designed to pulverize soft, fibrous and brittle materials. The mill develops extremely high centrifugal forces resulting in energy input that is up to 50 higher than in other planetary ball mills. It has a single grinding station for.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.
