High Pressure Grinding Rolls (HPGR)

The HPGR product corresponding to the best condition is submitted to the standard Bond ball mill grindability test The Bond ball mill grindability test measures hardness as an index regardless of the feed size so it does not give credit for the additional fines Therefore the index itself is ignored in the analysis and the results are assessed in terms of throughput rate or specific energy requirement
