Jan 01 2016 These roll crushers have large forces of compression and are called high pressure grinding rolls HPGR. The present trend is to replace secondary cone crushers by HPGR. The work at Polysius 3 and described by Friedrich and Baum 4 and Otte 5 indicates considerable metallurgical advantage in the extraction of minerals such as gold and ...
Jun 26 2019 High pressure grinding roll is designed according to the principle of inter-particle breakage by huge pressures. The pressure is from a pair of counter-rotating rolls with the same diameter and rotary speed. One is fixed while the other is allowed to shift front and back slightly. Pressures are worked on the bearing supports at the both ends of ...
