Modelling SAG Milling Power and Specific Energy Consumption

Especific energy modelling SAG mills operation data abstract Comminution, particularly milling, is on average the largest consumer of energy in mining. Actual com-minution circuits consist in most of the cases in coarse crushing, SAG milling, pebble crushing and sec-ondary ball milling. In these circuits the SAG mill is the largest energy

The SMC and Bond ball work index experiments as well as the Morrell model indicated that the order of the specific energy consumption of comminution was “Jaw crusher + HPGR mill + ball mill

ball mill capacity energy consumption

2021-8-2 A feature of ball mills is their high specific energy consumption; a mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, i.e. during grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity.

Comparing ball and vertical mills performance: An

seen, the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit. The averages were 11.3, 11.7 and 6.5 kWh/t respectively for ball mill 01, ball mill 02 and vertical mill. Figure 5 Net specific energy consumption of regrinding circuit.

applied. The calculations, presented in Table 1, showed that the expected specific energy consumption for the circuit was 13.5 kWh/t, based on the measured ore hardness, feed size, and product size. A specific energy consumption of 14.9 kWh/t was measured for crushing and grinding equipment while accounting for drivetrain

Comminution processes: Basics and application to energy

1. Specific energy of mill compared to new created surface energy → not meaningful, efficiency much smaller that 1% 2. Specific energy of mill compared to minimum specific energy requirement in so-called element tests. However, here at least two possibilities exist: a. breakage energy of single particle stressing by compression / by impact

crusher would provide this energy. However, in this situation the ball mill has to supply this energy and it has a different (higher) work index than the crusher (ie the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction). Hence from equation 7, to crush to the ball mill
