The decision to go single stage or two stage grinding is generally dictated by the product required. A guide based on grind size follows: 1. Coarse Grind Coarser than 80% passing 106 µm. If determined to be reasonably powerefficient, single stage SAG milling is likely to be the most profitable grinding circuit design. 2.

Operation of the AG/SAG mill in singlestage and twostage mode was then compared, both in closedcircuit operation. The twostage circuit was configured as SAG/AG grinding followed by ball milling (SAB or FAB) (Fig. 2). These comparisons have been made for GALIC with a coarser PSD sample (Fig. 4) and results are summarized in Table 9.

Single Pair Mill vs Double Pair Mill. From a functional standpoint, the difference between a single pair mill (or a 2 roller mill) and a double pair mill (or a 4 roller mill) is pretty minor. With a single pair, a single set of two rolls is being used to crush your grain. A double pair essentially does the same thing but with four rolls.
