Simba and Moys (2014) suggested that alternative shapes to balls can reduce the grinding costs and improve milling efficiency. Different grinding media produce mineral particles with different surface properties and floatability (Li and Gao, 2017). It was documented that the rod mill products have the most elongated and smoothest particle …Web
