Circuit Capacity of HPGR

The capacity of an HPGR circuit, as distinct from the unit capacity discussed above, is obviously a function of the circuit design. Of the above variables, the feed bottom size is particularly relevant in this regard, as a truncated feed necessarily implies the pres- ence of a screen or other classification device upstream of the HPGR.
