Each method must consider the basic design goals of HPGR mill design. CONTROL METHOD 1 – INDEPENDENT SPEED REGULATORS The most straightforward way to control the rolls is to have both drive 1 and drive 2 operate as individual speed regulators. In this arrangement both roll 1 and roll 2 drives will receive a speed reference from the
zIt was additionally shown that the ballmill dimensions predicted from the above methodology are almost equal to those of the Bond method. This fact is very important, because the various corrections, associated with the Bond methodology, are not necessary and the model developed can be used as an alternative method for ballmill scaleup purposes.
