### Kinetics Of Dry Grinding Of Industrial Minerals Calcite

This paper presents the kinetics study of dry ball milling of calcite and barite mineralshe experimental mill used was a laboratory size of 209 mm diameter, 175 mm length, providing a total mill volume of 6001 cm 3, with a total mass of 5kg of steel balls of 46, 26 and 12mm diameter, so as to occupy 20 of the mill volume and with a speed of rotation of 74 rpm.
