Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. ... The capacity, or throughput, of a ball mill is directly linked to particle size of the ball mill discharge. For example, it takes approximately 3 times as ...

With throughput in many cases worth more economically than sacing grind size, the focus shifts to throughput so much that the available ballmill power is often not used to the fullest extent. Even in those operations where a firm final grind size target is not adhered to, and attainable throughput governs the balance of the circuit, it is ...

mills and onto the secondary ball mill circuits, alleviating a common bottleneck. Modifying blasting practices to achieve a more suitable mill feed size which varies according to the crushing/grinding circuit can achieve up to a 30% increase in throughput. Following an initial benchmarking of an operation's practices,

In operations needing improved grinding circuit performance, the ability to fully utilise the available installed ball mill power will enable higher throughput, a finer grind, or a combination of the two, which will lead in turn to increased production and a corresponding increase in revenue. However, the practical considerations and costs of ...

With a batch mill, as previously suggested, the centre of gravity of the ball charge and powder charge sensibly coincide and so the density correction (1 + σ/q) previously deduced is applicable. In the grate mill the powder surface probably slopes from the inlet end of the mill to the discharge end in the manner indicated in Figs. and ...

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the ...

The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding. That is, for every incremental increase in circulating load of ...

Once you measure the ball charge and measure the total charges then you need to target an appropriate ball to rock ratio for a chosen mill throughput rate. With high aspect ratio SAG mills total charge to ball charge ratio should be greater than 2 (up to ) for a coarse mill feed (say F80 > 110 mm).
