Work Index Determination for High Pressure Grinding Rolls

The use of High Pressure Grinding Rolls is gaining significant interest as a replacement for SAG milling in the comminution of hard rock ores because of the potential for reduced costs in terms of energy and grinding ball consumption. Estimation of expected energy consumption for full- scale operations has conventionally involved the testing of a few fairly large samples in pilot scale HPGRs. This paper
