Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills. Rod mills have an industrial yield that is less than that of ...

Because rod mills provide some internal sizing action, they are commonly operated in open circuit. There is an increasing tendency to use an extra stage of crushing instead of a rod mill because crushers are more energy efficient. Wet ball mills are usually operated in closed circuit to .
· Rod mills are generally operated in an open circuit because of their grinding action, especially when preparing feed for ball mills. Ball mills, however, are virtually always operated in a closed circuit with some form of classifier. Various types of classifying device can be used to close the circuit, such as mechanical classifiers, hydrocyclones, etc. The AG/SAG mills can be operated in ...

mill circuit (Figure 1), this is achieved by taking a sample of cyclone underflow and a sample of ball mill discharge, and then running a screen analysis in the lab. For forward fed circuits ( primary ball milling), a size distribution of the combined mill feed (circuit new feed and c yclone underflow) is required. While not as straightforward as taking the CUF as total ball mill feed ...

Autogenous mills range up to 12 meters in diameter. The lengthtodiameter ratios in the previous table are for normal appliions. For primary grinding, the ratio could vary between 1:1and :1. For fine regrinding in open circuit, the ratio ranges from :1 to :1. Some ball mills are separated in to compartments by grates.
