Review of Related Literature Rice (Oryza sativa) is one of the leading food crops and a staple food for more than half of the world's population. Ninety percent of the world's rice production is geographically concentrated on the regions of Eastern and Western Asia (Prasad et al. 2017). China and India are the top two countries which supply over half of the world's rice production.

A review of the literature shows that there are numerous studies on energy consumption comparing conventional grinding systems and VRM in cement plants. It is worth noting that the VRM could save 30% energy in cement grinding [712]. In a test performed in the Loesche test center in Germany, copper slag grinding saved % energy in an

Research Highlights No considerable influence of speed ratio k in the range − 3 < k < − 1 on the grinding ball motion pattern was observed. Grinding ball motion is strongly affected by the friction arising, among others, from different feed materials. Friction necessarily has to be considered in studies on stress conditions in the planetary ball mill. Results suggest the possibility to ...

In total, 165 scenarios were simulated. When the mills charge comprising 60% of small balls and 40% of big balls, mill speed has the greatest influence on power consumption. When the mill charge is more homogeneous size, the effect of ball segregation is less and so the power consumption of the mill will be less affected.
