The design and scaleup of ball mills are important issues in the mineral processing industry. Incomplete knowledge about the mechanics of charge motion often forces researchers to rely on phenomenological modeling to formulate scaleup procedures. These models predict the behavior of large industrialscale mills using the data obtained in small laboratoryscale mills. However, the differences .
It accounts for up to 40% of the total power consumption in mineral processing plant operations. So, selecting the efficient solution for grinding section is very important. Prominer provides ball mill / rod mill grinding system which is widely used in various types of ores' beneficiation, electricity, cement and chemical industries.
The aim of this study was to develop a new method for assessing the Bond work index in a ball mill (BBWI), which is based on a first order kinetics present in the Bond ball mill for grinding mineral raw materials (Austin et al., 1981; Ahmadi and Shahsavari, 2009). Theoretical basis of quick procedure
