Sag and Ball Mills
Sag and Ball Mills contain heavy steel balls that break rock up until it resembles a fine powder. The mills look like large rotating drums. The largest mills used at Mt Isa are nearly 10 meters in diameter. Image courtesy of Xstrata Copper.
Optimization of mill performance by using
Mill power Usually, plant operators use mill power readings as an indior of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between

Ball Mill: Operating principles, components, Uses ...
05/07/2020 · The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
Modelling: Transfer size limits
For example, the SAG mill may have 10 MW of power draw available and the two ball mills each of MW of power draw available for a total of ratio of 10:15 (1:). The software uses the particular power model (Bond/Barratt, Morrell Mi, etc.) to determine what is the transfer size where the ratio of E SAG to E ball matches the ratio of mill ...

Ball Mills
A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation.
