Table 5.4 Summary of HPGR - ball mill circuits simulation results - "Comparison of HPGR - ball mill and HPGR - stirred mill circuits to the existing AG/SAG mill - ball mill circuits" DOI: 10.14288/1. Corpus ID: Comparison of HPGR - ball mill andComparison of the overall circuit performance in the .1/2/2011· In HPGR-ball mill circuit, when the compression of the grinding efficiency of HPGR and ball mill circuits separately, it can be seen that HPGR circuit is very efficient. Although VRM is also very effective grinding equipment, it consumes too more energy to transport the material from grinding table to dynamic separator by air inside the mill.Improved characterisation of ball milling energy requirements for HPGR .downstream ball mills can be significant (Patzelt et al., 2006). Schönert (1988) estimated that replacing existing circuits with HPGR-ball mill circuits could increase circuit capacity by 12-25%, and reduce energy by 10-20%. However, for this to be achieved theHPGR High Pressure Grinding RollsHPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores. .
