Semi-industrial tests ensure the most reliable information for calculating loads for equipment. However this requires a significant amount of ore samples a lot of labor and the pilot plants. Fred Bond published an article in 1961 which described the procedure for testing ores for a Bond Ball Index. This parameter is still one of the most demanded tools in the design evaluation and optimization of ball grinding plants around the world. However the testing methodology for the Bond Dall Index requires about 10 kg of sample the standardized equipment and takes an average of 6 to 12 hours. Many researchers have tried to find alternative methods for determining this Index - to reduce labor costs sample weight or to get one without standard equipment. This paper was carried out with the purpose of reviewing classifying and testing the existing methods for determination the Bond Ball Mill Index. The authors of the considered methods were Aksani B. and Somnez B. Todorovic D. Berry T. F. and Bruce .
