These test results show that Nano-particles can easily be produced with Planetary Ball Mills from FRITSCH . An intermediate sample after 30 minutes with the results x10 < 180 nm - x50 < 250 nm and x90 < 580 nm showed that FRITSCH technology makes it possible to turn a "boulder" into Nano-particles in just 1 hour.

Bouldern (englisch boulder „Felsblock") ist das Klettern ohne Kletterseil und Klettergurt an Felsblöcken, Felswänden oder an künstlichen Kletterwänden bis zur Absprunghöhe. Absprunghöhe ist die Höhe, aus der noch ohne wesentliches Verletzungsrisiko von der Wand zum Boden abgesprungen werden kann. Seit den 1970er Jahren ist das Bouldern eine eigene Disziplin des Sportkletterns und ...

well as the kinetic energy of the milling ball affected the size reduction; more collisions or higher energy resulted in a higher milling efficiency. The evaluation of the effect of the process parameters on milling efficiency was facilitated by the use of simple scaling factors. For example, all milling curves for samples with different WC amounts coincided when rescaling the milling time ...

It is well known that ball milling efficiency varies during the lifetime of the shell liner. For instance, the mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty.
