Ball Mill Power CalculationExample #1. Awet grinding ball mill in closed circuitis 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). In order to determine thepower requirement, the steps are as follows:
