Why HPGRs are revolutionising mill circuits
07/08/2019 These energy-efficient grinding machines are mostly used for processing iron, gold, copper and diamond ores, although they’re increasingly being deployed for lithium, limestone and vanadium. Despite having a significantly smaller footprint than conventional “tumbling” mills, HPGR’s are high-capacity crushing units delivering a high degree of size reduction, resulting from sophisticated ...
