PDF First choice for HPGR technology and service
A High Pressure Grinding Roll produces a particle size distribution (PSD) that is wider, with more fines, than a tertiary crusher (e.g. cone crusher) would produce. The reason is that the compressive force not only acts on the coarse end of the PSD, but throughout the particle bed on both coarse and fine particles,
