Effect of grinding methods on powder quality of king

2018-3-16  The grinding experiments were performed using a laboratory scale ball mill. Quality of the powders was accessed by measuring the properties such as densities, Hausner ratio, compressibility index, particle size distribution, colour change, microstructural changes, and mineral compositions. Bulk density (483 kg m −3) and tapped density (556 kg m ‒3)
