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 .

Ball Mills vs Rod Mills

03 07 2017  Rods in place weigh approximately 400 pounds per cu ft and balls in place approximately 300 pounds per cu ft. Thus quantitatively less material can progress through the voids in the rod mill grinding media than in the ball mill and the path of the material is more confined This grinding action restricts the volume of feed which passes
