The results showed that the HPGRball mill circuit achieved a 21 reduction in energy consumption over the existing SAGball mill circuit at the same P80 grind size of 160 mircons μm At a grind of 80 passing 75 μm the HPGRstirred mill circuit showed a 34 reduction in

The high unit capacity SAG millball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs which has in turn made many lowgrade hightonnage operations such as copper and gold ores feasible Future circuits may see increasing use of high pressure grinding rolls Rosas et al 2012

The wear parts within our High Pressure Grinding Roll are longlasting but also very easy to replace when they do wear down Up to 2030 reduced energy consumption Energy efficiency is key to running a profitable operation so saving 20 to 30 could pay huge dividends

and SAG mill circuits in hard ore applications by P Rosario† and R Hall† Synopsis The application of high pressure grinding rolls HPGR has been growing in the mining industry for the last 10 to 15 years The major benefits supporting this trend are better energy efficiency improved grinding capacity and higher metal recovery in

This efficiency combined with escalating energy prices steel prices and the requirement to process larger lower grade deposits has necessitated that better comminution techniques are found to challenge the dominant position of AGSAG mills in the grinding circuit Recent advances in high pressure grinding rolls HPGR particularly in terms

Trade­off studies of multi­stage crushing plants involving high pressure grinding rolls HPGRs versus semi­autogenous grinding SAG mill circuits typically focus on the operating cost savings of crushing plants versus the capital cost savings of SAG mill plants Very high­level or desktop

This report is a tradeoff study to evaluate the application of High Pressure Grinding Rolls HPGR as an alternative technology to the conventional semiautogenous grinding SAG milling process for the Morrison Project The processing plant is designed to operate

High Pressure Grinding Rolls HPGR is a mature technology that is proven to reduce capital and operating costs in full scale plants when compared to other comminution technologies SGS comminution experts have developed a simple testing methodology to

• two stage crush ball mill eg Pajingo • 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

Mill application features Frozen charge protection – Detects frozen charge in the mill minimizing equipment wear and liner replacements Coupling supervision – Detects if a failure or slippage occurs in the couplings and stops the system in case preventing major damages Standstill detection – Prevents the motors from restarting if the mill is still rocking or moving after a stop
