The HPGR, developed by FL, ranks among the most advanced and efficient crushing units available. HPGR equipment is a modern and very energy-efficient comminution technology. During its relatively short history, HPGR technology has undergone significant development with machine roll wear surfaces & control philosophy.
High-pressure grinding roll presses (HPGRs) are emerging as an important comminution technology in the minerals processing industry. The technology has found its key application in the liberation of diamonds and also in primary comminution. Compared with conventional grinding, the HPGR process consumes significantly less energy, which in turn leads to a reduction in operational costs coupled ...
