The high-pressure grinding roll (HPGR) is a type of roller mill that continuously produces particle-bed comminution. Since the capacity of the HPGR is determined by not only operating conditions but also the roll geometry, knowledge of the effectiveness of the roll geometry is still limited.Web

The high pressure comminution process causes micro-cracks in the particles, which lead to the liberation of minerals and a higher portion of fines. HPGR treated minerals show better leaching performance, because the micro-cracks increase the particle contact surface for the leaching liquid. Also, flotation efficiency is further enhanced through ...Web

Pelletization is one of useful processes for the agglomeration of iron ore or concentrates.
