High pressure grinding rolls. The high pressure grinding rolls, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.
As grinding plays an essential role in minerals processing, the need for innovation in grinding is critical to circuit optimization. The HRC™e high pressure grinding rolls (HPGR) is combining proven technology with a customer-focused evolution for superior grinding and energy efficiency to help optimize your operations.
