Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce 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 volume, exceeding its.
Mar 27, 2017 Place the bottle test on bottle roller machine and start the rolls. If than one cyanide leach test is in progress, add a sleeve onto the neck of each bottle, then lower each bottle to allow air into the bottle when it touches the bottom of the top bottle on the rolls. At the end of each timed interval, repeat steps 11 through 15.
