ABSTRACT:
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 particle size distribution including particles in a range of about 75% to about 90% by weight greater than 200 mesh to produce a limestone product. Optionally, particles larger than about 14 to 16 mesh are removed, in a separator, and refed to the roll grinder.
