According to [26], when grinding in a ball mill, the reduction in size occurs according to three mechanisms of fragmentation: abrasion, splitting, and destruction ( Figure 3) In 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 procedureQUICK METHOD FOR BOND WORK INDEXAPPROXIMATE Probability of fracturing of glass spheres Breakage function of single limestone as function of impact velocity (stress energy) particles for different reduction ratios Specific work or specific force (= Stress intensity) of single particle Tumbling mill Vibrating mill Planetary ball mill Stirred ball mill Mills with loose grinding minution processes: Basics and application to energy
