Ball mills, conversely, contain grinding media up to 50mm in diameter, occupying between 25% - 40% of mill chamber volume. To effectively reduce material size, each type of mill needs to generate different charge load actions, or the type of motion characterised by the mill's contents. SAG mills generate higher levels of impact reduction and ...

Anyone wondering how Bond ball mill work index compares versus SPI or JK A*b? Well, M. Doll says, several comparisons have been published, such as at CMP 2011 and Procemin 2009 and in general, the Wi_BM is not compatible with the other two because they measure different size classes. The Bond ball mill work index measures …
SAG mills grind ore by lifting it and a small amount of grinding media and dropping it inside a horizontal mill. Ball mills are smaller and use a higher concentration of iron balls to pummel the ore. The mills can operate in an open grinding circuit, feeding secondary grinding systems, or in a closed circuit generating a fine product.

What is the difference between a SAG mill and a ball mill? A SAG mill uses larger rocks or ore fragments as grinding media, while a ball mill uses smaller grinding media such as steel balls. Additionally, a SAG mill uses a minimal ball charge of 6 to 15%, while a ball mill requires a higher ball charge of 20 to 40%.
By mill we refer to Ball Mills, Rod Mills and SAG Mills. ... The difference between the two is the weight that is on them and the speed that they turn. Because the weight that is on the two surfaces of the bearing isn't great enough to force the oil out from between them they do not require oil to be forced in between the two surfaces on ...
Another major difference between raw mill and cement mill is the equipment used to grind the raw materials into clinker and cement, respectively. In the raw mill, vertical roller mills are used to grind the raw materials into fine particles. On the other hand, in the cement mill, ball mills are used to grind the clinker into a powder.
