For tumbling mills the specific comminution energy (Wi) relates to the power at the pinion or for gearless drives the motor output. For HPGRs it is the energy inputted ... 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

For a single mine, average comminution energy consumption can be approximately 6,700 kWh /kiloton. G r i n di ng is a c co mp li s he d b y a b ra s io n an d i mp a ct o f t h e o re
mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential ...
comminution energy requirements of gold and copper producing mines at the 2014 Mill Operators'' conference in Townsville. His work provides reliable benchmarking data that can be used to compare comminution energy consumption across different minesites. The total gold and copper production of the mines included in the study equated to 15% and 24%
The parameter M i takes on different values depending on the comminution machine: M ia for primary tumbling mills (AG/SAG mills) that applies above 750 μm; M ib for secondary tumbling mills (, ball mills) that applies below 750 μm; M ic for conventional crushers; and M ih for HPGRs. The values for M ia, M ic, and M ih were developed using the SMC Test® combined with a database of ...

Cement grinding Vertical roller mills versus ball mills. It is characteristic of grinding in vertical roller mills that the energy input to the material per pass between roller and table is small, for which reason a large number of passes are required to obtain the necessary specific energy input to the material.
mills with the rod mill and ball mill laboratory work indices. Note, in Figure. 1, that the rod mill product slope is less than due to an extra amount of nes present being fi fi ner than 650 μm. These fi nes proceed to the ball mill improving the ball mill effi ciency. Also, the plotted rod mill P80 value, as shown in Figure 1, is 2900 ...
very fine particles, the specific energy consumption of stirred media mills is less than that of tumbling ball mills. The importance of stirred media mills increases steadily because of an increasing demand for fine and very fine particles and because of the advantages of stirred media mills compared with other mills.
