Improved characterisation of ball milling energy

The ball milling requirements of HPGR and standard crusher products are measured. • Methods for assessing the energy consumption of the Bond Ball Mill are discussed. • The average reduction in Work Index of HPGR products was 1.9 kWh/t. • A similar magnitude of reduction was observed in the Size Specific Energy. •

Effect of High Pressure Grinding Rolls (HPGR) pre-grinding

Jun 01, 2016 High pressure grinding rolls (roller presses) are used in both cement raw materials (limestone, clay, shale etc.) and cement grinding stages. The energy consumption is 2.5–3.5 kW h/t and about 10 kW h/t when recycling of the material is used.A HPGR consumes 30–50% less specific energy as compared to a ball mill which indicates higher comminution efficiency for a HPGR.

Enduron® HPGR

Feb 02, 2021 For gold mines using carbon-in-leach (CIL) processes for recovery, we’ve found the best results are achieved with a HPGR performing tertiary grinding before a ball mill further reduces the product. In this role, the HPGR significantly uplifts the capacity of the circuit and provides flexibility both in dealing with feeds that a ball mill

FIRST YEAR OF OPERATION OF HPGR AT TROPICANA GOLD

o HPGR was expected to consume less energy per tonne of ball mill feed compared with conventional solutions o It was also expected that ball mill specific energy consumption would be lower (compared with conventional solutions), this resulting from incipient cracks present in BM feed particles • High mechanical and process availability

Effect of HPGR Breakage on Metallurgy Minerals Engineering

May 17, 2016 The results showed that the HPGR ball mill circuit achieved a 21% energy reduction over the existing SAG ball mill circuit under the same P80 grind size of 160 μm. There is also a well-known HPGR application at Cerro Verde copper mine in Peru which has been presented by Vanderbeek et al. (2006) in detail.

Optimization of HPGR-Based Clinker Grinding Circuit at

Recently, in a retrofit project, two high pressure grinding rolls (HPGR) units were installed in two grinding lines before the tube ball mills to grind clinker feed. The efficiency of these HPGR units is reported to be under design specification.

HPGR High Pressure Grinding Rolls

Jul 13, 2016 HPGR test results published by Grier (1992) on gold ores from the Mt. Todd project showed significant energy savings for a HPGR/Ball Mill circuit as compared to a SAG/Ball Mill plant. By adding a Polycom high-pressure grinding roll, the throughput of existing plants can be increased by as much as 150% while simultaneously reducing the power
