If you haven't checked rod side clearance, insert a feeler gauge between each pair of rods on each crank journal (see Step 24 for clearance recommendations). You can also verify the accuracy of rod-journal "indexing" on your crankshaft. First, double check the accuracy of your TDC pointer on cylinder number-1 (Step 27).
Since there are not that many small SAG mill operations of under 2000 TPD, and most sub-2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <1.5″ (40 mm) and often as finely crushed as <3/8″ (9 mm).
