## Calculation of Grinding Balls Surface Area and Volume

The volume of a grinding ball is determined by the formula: V=4/3*π*R 3, where: V the volume of the ball π — PI constant, a mathematical constant that is equal to the ratio of the circle’s circumference to its diameter 314 is a commonly used value for PI; R the radius of the ball Earlier, we have mentioned one of the grinding media characteristics which is defined by the ratio of
