Grit Size to Micron Chart. Very fine and not used often commercially. Mainly for contest cutting or hobby cutters. Seldom needed. Seldom used. 50,000 grit is more common and used for polishing sapphire and other hard materials. This is the standard commercial polish for sapphires, although I recommend going another step to 50,000.
Fine Grinding Considerations Fine grinding materials–down to the micron, sub-micron, or even into the nano level–is more complex than just reducing particle size. First, knowing and understanding the existing properties of the material to be processed is vital in order to select the right equipment.

(Impact, Shearing, Attrition) Space saving: 65% more compact compared to past models. (Compared as a whole system) Low Noise level : under 85dB. Equipped with contaminant separation mechanism.
Conducting a Bond test at a limiting screen of 25 microns implies that you are targeting a grind of - 80% passing 20 microns. Balls mills are very inefficient at that grind due to the coarser ball size used. Explore different fine milling technologies ( SMD, Isamill, Deswik) which have their own testwork.
