Has any one ever successfully using ball mill to reduce ceramic flake from 100s microns down to 10s-20s microns without turning them into ultra-fine powder? I've put this question in Google and what it turns up are generic ball mill stuffs. Any good references will be very appreciated. Thank you!
P.S. although I can't share the composition of our flake due to the nature of my project, what I can share is that the flakes are non-reactive in neutral aqueous environment and ambient temperature/environment. The flakes are not super hard like tungsten or alumina, but have fair amount of hardness. We plan to use a high-energy, planetary ball mill.
With a ball mill you get particles of all sizes, it is impossible to choose a specific size.
Nevertheless, your task is not hopeless. However, you do not need a ball mill for this, but rather a vibrating sieve machine with stainless steel sieves, for example this: https://www.retsch.com/products/sieving/sieve-shakers/as-200-basic/. The crushing in a sieve machine also takes place using ceramic balls that are placed on a sieve together with the ground material. By using several sieves with specific mesh sizes, you get the desired particle size.
