Read MoreUnited States power consumption is related to comminution (Comminution and Energy Consumption, 1981). With this in I mind it is understandable that one would want to control a grinding circuit so that the energy required to process a given ton of ore is optimal. .Furthermore, overgrinding an ore and the subsequent production of fines can reduce the

Read MoreFigure 2: Ball mill for determining Bond ball mill work index 1 For the purists, there were two models in existence at the time: the Von Rittinger and Kick models. Neither of these gave results that matched the observations of specific energy consumption from tumbling mills. 2 F.C. Bond; The Third Theory Of Comminution, Transactions AIME 1952 ...
