The grinding circuit applications of Polycom HPGR units for mining applications have been described previously by Patzelt (1987), Otte (1988), and Otte & Patzelt (1991). Following are several options for the use of the Polycom high-pressure grinding roll for optimization of gold ore …

Concassage : définition. Action de concasser, c'est-à-dire de réduire en petites parties (jusqu'à quelques millimètres), avec un outil (marteau, pilon), quelque matière dure ou sèche, comme le sucre, le poivre, les graines, céréales, etc.

Robust HRC™ high pressure grinding rolls (HPGR) High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed ...
