Energy and Cost Comparisons of HPGR based Circuits

Up until now tumbling mills such as AG/SAG mills and ball mills have had a dominant bearing on the design and economics of comminution circuits However it is commonly agreed that the majority of employed comminution processes are energy intensive and energy inefficient accounting for up to 80 of overall process plant energy consumption and having an efficiency of as low as 1 .
