Jan 01, 2016 The present trend is to replace secondary cone crushers by HPGR. The work at Polysius and described by Friedrich and Baum , and Otte indicates considerable metallurgical advantage in the extraction of minerals such as gold and copper by the use of high pressure grinding rolls. In this chapter, these two types of roll crushers are described.
The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid […]
