Opening up the secondary crushing circuit to a P80 of 30 mm or 40 mm but with a coarse top size could well be acceptable for a large scale HPGR, and would certainly be worthwhile investigating at a pre-feasibility optimization. However, one has to keep in mind that the capacity also is affected by the selection of roll diameter.
