How Hpgrs Compare To Conventional Milling

Aug 19,   within comminution circuits, high pressure grinding rolls (hpgr) are increasingly replacing conventional sag, rod and ball mills for hard rock reduction – owing to their substantially lower energy consumption and potential for significant total cost of ownership reduction. not only do they require as much as 40% less energy than traditional reduction methods, but their wearable.
