Abstract. This paper describes a method for assessing the downstream milling energy requirements for high pressure grinding rolls (HPGR) products based on a Bond mill test procedure. Multiple tradeoff studies have reported the performance of HPGR versus SAG milling with energy savings of between 11 and 32 per cent.
