Ball Mill Design/Power Calculation
Ball Mill Power Calculation Example #1. 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).
MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING
Ball mill = coarse particles (in the plant ball mill) grinding efficiency Ore grindability (in the lab ball mill) The units of "ball mill grinding efficiency" will be covered in detail in the first part of the module. Alternatively, we can say that: Specific grinding rate = Ball mill x Ore grindability
