Improving Power Consumption In Ball Mill

Charge behaviour and power consumption in ball mills ...

01/08/2001  Typical power consumption for a 5-m diameter by 7-m-long ball mill is between 2.5 and 3.5 MW. The actual proportion of this energy usefully used in size reduction is thought to be very low, perhaps in the range of 1–5%. Significant financial and environmental benefits can be obtained by improving this efficiency even slightly.

01/08/2001  The specific power consumption for these two ball shapes is shown in Fig. 16. For N≤75% there is no change in the mill power draw. This occurs because the center of mass of the charge is little changed by the particle shape at these speeds. At intermediate speeds, the power draw for the non-circular balls falls off rapidly. This reflects the ...

Quantifying and improving the power efficiency of SAG ...

01/02/1994  A quick glance at Rowland efficiency factors shows that operating a ball mill at conditions other than the optimum will result in an increase in the unit power consumption of the mill, and a decrease in circuit power efficiency. SAG mills, on the other hand, rarely approach the efficiency of a ball mill. Breakage mechanisms are not nearly so well defined, and while it is possible to influence ...
