Study of Comminution Kinetics in an Electrofragmentation Lab-Scale Device

A significant challenge in mineral raw materials comminution is the improvement of process energy efficiency. Conventional techniques, although globally used, are far from being considered power-efficient. The use high-voltage electric pulses a concept that worthy study; despite its lack industrial-scale validation after several decades lab-scale research, it seems promising as pretreatment leading to savings. In this article, Cumulative Kinetic Model methodology adapted model effect an electrofragmentation device, and study dunite rock ore. results show product particle size distribution (PSD) can be predicted with reasonable accuracy using proposed model.
