Pulverising and Grinding

Although most quarrying operations seek to limit the amount of fine limestone produced, there is a demand for pulverised and ground limestone. 

Pulverised limestone may be produced economically in impact crushers, such as hammer and beater mills. For use in agriculture, the product should be at least 95 % less than 3.35 mm and substantially less than 600 pm (see chapter 10).
