Ball milling: a green technology for the preparation and
网页Ball milling was performedfor 24 hours at 1000 rpm. With this pre-treatment, the resultingnanocrystals had a spherical shape with a 100–200 nm diameterand a 3–7 nm height, rather than a rod-like shape. Thisdemonstrated that the applied pre-treatment was a determiningfactor in the morphology and particle size of the resultingCNCs.

Ball Mill Critical Speed 911 Metallurgist
网页2015年6月19日 Critical speed is C.S. = 76.63 / 11^0.5 = 23.1 rpm Ball and SAG Mills are driven in practice at a speed corresponding to 60-81% of the critical speed, the choice of speed being influenced by economical considerations. Within that range the power is nearly proportional to the speed. Mill rotating speed impacts grinding rates.
