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 material to the desired smaller grain size.

Feb 01, 2006 1.. IntroductionSchönert (1979) has shown that the most energy efficient method of comminuting particles is to compress them between the two plates. Compressing a particle bed between two counter rotating rolls was achieved by the invention of the high pressure grinding rolls (HPGR) (Schönert and Knobloch, 1984).The first commercial application of HPGR was in 1985 and its success

Summary: This paper presents the effect of operational parameters on the performance of a closed circuit HPGR. For this study, six surveys in a cement grinding circuit operating in Turkey were performed. The relationships among operational parameters like gap, pressure and capacity and the effect of these parameters on the performance were investigated.

Abstract Results obtained from a laboratory-scale high pressure grinding rolls show that the specific energy consumption of the rolls increases linearly as the applied grinding force increases, but this is not accompanied by a linear increase in the size reduction achieved. Instead the latter increases at a gradually reducing rate, which is shown to be best described by a power-law equation.
