Jun 03, 2013· When you change material, your grinding technique can change. For instance, because stainless steel conducts heat the way it does, a grinding wheel can heat up and blue the metal surface before you know it. If it’s a cosmetically important area, you may need to go back and regrain or polish the entire surface.
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.
