A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).

Grinding, particularly at finer sizes to achieve the required degree of liberation or specific surface, is a critical unit operation in terms of energy consumption and process optimization.

To grind the given material to a smaller size using a ball mill and to obtain the size distribution of the initial and final mixture by sieving. Standard sieves of specified opening sizes are used. Size reduction is the most inefficient unit operations in terms of energy.
