Q: What are the main advantages of using a tumbling mill over a ball mill? A: Tumbling mills are generally more cost-effective and energy-efficient than ball mills, especially for coarse grinding. They are also more versatile and can handle a wider range of materials and particle sizes. Q: Can a ball mill be used as a tumbling mill?

In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is 0.6% of the total energy supplied to the mill setup.

Further, Attritor tanks are all jacketed which allows for more precise temperature control during high energy ball milling. The savings in energy and the increase in grinding efficiency provided by Attritors are substantial. The graph below compares various mills during the high energy ball milling process.
In addition, no measure of ball mill circuit performance is complete without including an ore grindability component. The functional performance equation (Equation 1) includes ore grindability in the mill grinding efficiency metric. Mill grinding efficiency is essentially the mill grinding rate (t/kWh) normalised by a grindability value (g/rev).

What are the dimensions of the ball mill you are looking at? 40% ball charge is quite high (unless you are looking at a small mill). A difference (duty vs. maximum) of 5% to 10% is fairly typical and you would likely struggle to perceive an energy efficiency difference between the two operating points. Beyond this, the situation may change.
