Bauxite grindability at elevated temperature in various …

 · However, in several cases, where the bauxite is soft and a relatively coarse product is sufficient, rod mills are used for bauxite grinding. In order to investigate the applicability of the Universal Hardgrove mill for the prediction of specific energy and throughput of rod mills, a heat insulated Bond Rod Mill was constructed at the Institute in 2011 ( Mucsi et al., 2013 ).
