Preparation and Characterization of Nano structured

The size reduction of fly ash from micrometer level to nano levels has been achieved by high energy ball milling. The average particle size has been reduced from 60 μm to 148 nm, a reduction of nearly 405 times in magnitude, by this process. The surface area shows a tremendous increase by around 102 times in magnitude. The total surface free energy has increased by 300% after ball milling for

EFFECT OF BALL SIZE DISTRIBUTION ON MILLING PARAMETERS

size on milling rate for a South African coal. A series of batch grinding tests were carried out using three loads of single size media, i.e. 30.6 mm, 38.8 mm, and 49.2 mm. Then two ball mixtures were successively considered. The equilibrium ball mixture was used to investigate the effect of ball size distribution on the selection function whereas the original equipment manufacturer
