The ore pebbles produced are then used in the grate discharge secondary pebble mill as grinding media. The pebble mill operates in closed circuit with hydro cyclones, with a circulating load of about 140% of total feed. The mill design power draw is 4000 to 4400 kW, with 4500 kW installed power. Design charge level is 30-40 vol-%.
pebble mill (PM) each. The primary objective of the grinding circuit is to grind as much material within a certain particle size distribution. According to Bond's equation, the more energy is put into the system, the finer the product one obtains. Generally speaking, higher fill level and speed of the mill lead to more energy
This scenario considers the use of HPGRs and a pebble mill circuit in the iron mining sector, which can reduce process electricity use by 22% (Ballantyne et al., 2018; McNab et al., 2009). The various parameters used for the CSE calculation are shown in Table A12 in the supplementary file.
