##tihuan2##HPGR can replace the tertiary crushers or, as a pre-grinding stage, provide feeds for ball mills [[8], [9], [10]]. In an HPGR, energy consumption for a particle size reduction is based on the existing pressure between the floating roll (the moveable roll) and the fixed roll in the frame. This pressure can be varied from 5 to 18 MPa.
