Model:Morrell Hpgr And Ball Mill

Ball mill circuit: GMSG, 2016. Discussion. This model requires that the product of the secondary crusher and HPGR be coarser than 750 µm. This is reasonable as no HPGR circuit operates anywhere near that size range (as of 2020). There is a minor correction required for open circuit secondary crushing (the 1.0 factor becomes 1.19).

High Pressure Grinding Rolls (Hpgr)

High Pressure Grinding Rolls (Hpgr)

HPGR technology as an alternative to crushers and mills HPGR technology is a qualified alternative for large-scale comminution circuits and is becoming increasingly popular. The technology's working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the ...
