Flowsheet considerations for optimal use of high pressure grinding rolls

Abstract High pressure grinding roll (“HPGR”) technology is very rapidly gaining a wide acceptance within the mineral processing industry Benefits, including a superior energy efficiency and a lower overall operating cost of an HPGR based circuit compared to alternative technologies have been demonstrated at a number of operationsIn a previous paper (Morrell, 2008a) an approach was described which enabled the specific energy of tumbling mills such as AG,SAG and ball mills to be estimated from laboratoryderived ore characterisation data The following paper extends this approach to encompass jaw, gyratory and cone crushers as well as High Pressure Predicting the overall specific energy requirement of crushing, high
