High Pressure Grinding Rolls (HPGR) HPGR c<strong>on</strong>sists <str<strong>on</strong>g>of</str<strong>on</strong>g> a pair <str<strong>on</strong>g>of</str<strong>on</strong>g> counter rotating rolls, <strong>on</strong>e fixed <strong>and</strong> the other floating. The feed is introduced to the gap in between the rolls <strong>and</strong> they compress the bed <str<strong>on</strong>g>of</str<strong>on</strong>g> <strong>particle</strong>s.The grinding force applied to the crushing z<strong>on</strong>e is c<strong>on</strong>trolled by a hydro-pneumaticspring <strong>on</strong> the floating roll. Speeds <str<strong>on</strong>g>of</str<strong>on</strong>g> the rolls are also adjustable to obtain optimum grinding c<strong>on</strong>diti<strong>on</strong>s.
