High pressure grinding rolls—applications for the platinum

layout. In an industrial application on hard iron ore, AG mill throughput increased by 30% by installing a HPGR in such a circuit.1 Concepts for an HPGR—ball milling circuit High pressure grinding rolls can be built with throughputs of up to 2 000 tph and more per unit. Thus one HPGR can replace several tertiary crushers at the same time HPGR.
