High Pressure Grinding Rolls (HPGR) Mining SGS

High Pressure Grinding Rolls (HPGR) is a mature technology that is proven to reduce capital and operating costs in full scale plants when compared to other comminution technologies. The use of a small locked cycle scale test, such as the Bond ball mill grindability test, was proposed as an alternative way to achieve the same objective in a more controlled manner, and more importantly, with a smaller sample.

Mill (grinding)

High pressure grinding rolls. A high pressure grinding roll, 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.
