1. Introduction. Grain milling might be the oldest manufacturing process in the world. Archaeologists have found drawings, dating back to 2600 BC, of the basic process of rubbing or grinding using two stones on the walls of Egyptian tombs (Walker Eustace, 2016).Grinding (milling) of cereal grains is the fundamental operation currently used to produce flour, which is an ingredient in many ...

Red phosphorus (RP) is regarded to be a promising nextgeneration anode material for LIBs because of its cheapness, ... (VCC) and high energy ball milling (HEBM). The VCC strategy is limited, because the conversion between RP and white phosphorus (WP) is reversible reaction, which leads WP cannot be completely converted to RP.
