Circuit Capacity of HPGR uradoras-de-roca.com

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.

Quantitative Mineralogical Comparison between HPGR and ...

The use of HPGR, followed by a BM, generated a higher proportion of fines, and thus, a higher amount of liberated ore minerals. Grinding products obtained with both HPGR and a BM produced a high liberation degree in cassiterite, tantalite, and columbite in the fraction of particles of −250 µm, but low in the fraction of coarser particles.
