Grinding laws

Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing, one example being the Sepro tyre drive Grinding Mill. Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, [4] drawing approximately 0.0011% of the total world's power (see List of countries by electricity consumption ).

SAG mill Archives

The SAG mill trommel screen oversize feeds a pebble crushing circuit which returns crushed product to the SAG mill feed conveyor, the company said. The milling circuit, meanwhile, is fed with (F100) 250 mm primary crushed material from the primary stockpile at a throughput rate of 300 t/h and produces a product size of 70% passing 75 μm, which is fed to the differential flotation circuit.

Energy Curve Enhancement Blog 7: Including grinding …

In relation to the electrical energy consumption, SAG mills had the highest proportion embodied energy, followed by ball mills and stirred mills. The effect of circuit type on media consumption was also analysed, however, no clear difference in media wear for particular circuit types could be inferred from the current dataset (see Figure 2 ).
