VolPort, the leading enterprise of Chinese crushing and grinding industries, has always been dedicated to the development of ore crushers, sand-making machines and industrial grinders in the past 30 years.
For SAG mills, evidence shows that that feeding rate has a small effect on the final product size and that a maximum flow exists in order to generate a stable operation. This is due to the fact that when you increase the feeding flow an increase in the crushing rate is produced. This eventually generates a steady operation.
SAG mills usually have a larger diameter than length and are used to reduce large feed size ore (typically ~300mm) down to ~3mm, often for further grinding in a secondary process. Ball mills are smaller in diameter than length and can be used in either primary, secondary or tertiary grinding applications to reduce material from ~20mm to very ...

As you know these kinds of steel balls are resistant to impact but at a certain radius (worn balls) the spherical shape of balls will be change to irregular shapes which can affect grinding efficiency badly. So the ball size distribution inside SAG mill will be incomplete. For compensating this issue, extra ball size can be added with top size.
SAG milling extends itself to many applications due to the range of mill sizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these ...
In the case of SAB/SABC circuits the transfer size is the product of the SAG mill circuit and the feed of the ball mill circuit. Hence if power-based equations such as eq. 1 and eq. 2 are to be used to predict the SAG mill circuit and ball mill circuit specific energies it is. Whats The Difference Between Ball Mill Rod Mill And Sag
By combining with SAG discharge and screening on the SAG discharge screens, top size control to the ball-mill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006). A variant of this method is …

In a way, the media size should be selected based on feed size and grate opening. Finer feed (i.e. secondary crushed) justifies a 4" ball but if the grate opening is 60 mm x 100 mm slots then a 4" ball won't last very long. If …
With high aspect ratio SAG mills total charge to ball charge ratio should be greater than 2 (up to 2.5) for a coarse mill feed (say F80 > 110 mm). If the mill feed size is fine, say 50 mm or 30 mm, then you are looking at a total charge to ball charge ratio of about 1.5-1.6.

Amstar SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW. Our team of product engineers ...
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
