Energy and Cost Comparisons of HPGR-based Circuits | E & MJ
For comparison, the costs for SABC circuits grinding to 160 μm and 75 μm were determined to allow for direct comparison to HPGR-ball mill and HPGR-stirred mill circuits, respectively. The indirect cost was estimated at 45% of direct capital costs and was considered to be within industry standards for the options considered.

How to choose between sand mill and ball mill?
The results show that the sand mill is far superior to the ball mill in terms of grinding efficiency and preparation cost. The sand mill can produce a powder with an average particle size of less than 0.5μm, which is far smaller than the particle size of the product obtained by the ball milling mechanism. Next, we use an experiment to compare ...

What's the Difference Between Ball Mill, Rod Mill and SAG ...
The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. 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 ...
