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.

Ball-Rod Mills, based on 4″ liners and capacity varying as 2.6 power of mill diameter, on the 5′ size give 20 per cent increased capacity; on the 4′ size, 25 per cent; and on the 3′ size, 28 per cent.

performance equation (McIvor et al., 1990), the absence of a performance parameter to isolate ball mill grinding efficiency handicapped efforts to study the effect of any ball mill design or operating variable. Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change.

Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where D m = the …

to ball filling variation in the mill. The results obtained from this work show, the ball filling percentage variation is between 1.2– 3.7% which is lower than mill ball filling percentage, according to the designed conditions (15%). In addition, acquired load samplings result for mill ball filling was 1.3%.

If, on the basis of these results, we want to determine the energy required for grinding a milling product of size P= 104/~m, the following procedure should be applied.

equitions to estimate ball mill cost 9894. The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a predefined media and ore charge. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits. The test requires a minimum of 10kg of sample that has been stagecrushed ...

Tower Mills: 0.5"-1.5" grinding balls are recommended. The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1" grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls).
