VertiMill Sizing Example - Mineral Processing & Metallurgy Regrinding concentrates to a fine size is difficult to compare to a ball mill. The main reason for this is the extreme unpredictability of the quantities to be reground and their hardness as the grade, recoveries, and flotation response all combine to make the circuits unstable.
