Ball Mill Experiment Calculation

In this experiment, coarse salt will be placed into the ball mill. With the aid of metal balls of different sizes, coarse salt will then be comminuting into fine powder where the size particle of salt is determined using sieve nest .Sieve analysis is a method used to determine the particle size distribution of a granular material and in this experiment, the granular material is coarse salt.
