Selection oof Comminution Circuits for Improved Efficiency• a crushing circuit including high pressure grinding rolls (HPGR) at Argyle Diamond Mine. Recent feasibility studies for the Boddington Expansion Project have considered the use of HPGR for hard rock multistage crushing and ball mill circuits at high tonnage rates (Parker et al, 2001).
High Pressure Grinding Roller Market is to Reach US ...The high pressure generates a substantial amount of fine material as it causes the boundary weakening in the feed material and formation of microcracks. High pressure grinding rollers are now commonplace in the briquetting, cement, diamond, and iron ore sectors. High pressure grinding rollers include two rolls mounted in a sturdy frame.
More crushing less grinding | GekkoNov 12, 2012· Many traditional grinding technologies such as SAG mills are very energy inefficient with less than five per cent of the total energy in grinding used in rock breakage (Alvarado, S., et al, 1998). Where mineral liberation characteristics allow coarser liberation, it can be advantageous to use fine crushing technologies and eliminate grinding.
