Can the current SAG mills be replaced with High Pressure Grinding Rolls (HPGR) for producing Zinc and Lead Concentrates? Will the equipments have to undergo any change when HPGRs are used instead of SAG mills? Can someone illustrate the points to be considered while making a decision?

HPGR is not a replacement for SAG milling - different reduction ratios and cost.  HPGR are expensive per unit of mass treated and not good secondary size reduction equipment.
