A novel process for grinding limestone to a predetermined particle size distribution is disclosed. The process comprises feeding a feedstock of limestone to a roll grinder having a pair of opposing rotating rolls having a smooth surface, the rolls being separated by a predetermined nip or gap and having a predetermined circumferential velocity, and grinding the limestone between the rolls to a ...

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.
