Particle size distribution and structural changes in

Jan 10, 2014 Based on particle size distribution, it was concluded that the suitable condition for the dry grinding of limestone took place with balls of 10 mm diameter and revolution speed at 200 rpm. After 30 min of grinding under this condition, the mean particle size was reduced from 134 to 9 μm and the dispersion factor reached a value near to 25.
