Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond''s Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied. The test is a closedcircuit dry grindability test performed in a standard rod mill.

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills 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 of a ball mill.

Dry batch milling tests were performed in a laboratory scale ball mill measuring by cm. The mill specifications are given in Table 1. A constant ball load of 20% was maintained in all the tests with a ratio of for binary and for trinary ball mix.

the mill power and the efficiency of the mill operation (Van Nierop and Moys, 2001). If a SAG mill has been designed with a conventional power or specific energy model which do not consider the projected feed size distribution it is likely that this mill will reach the expected power consumption .

Describe the components of ball mill. Explain their understanding of ball mill operation. Explain the role of critical speed and power draw in design and process control. Recognize important considerations in ball mill selection. Reading Lecture. In ball mills, steel balls or hard pebbles to break particle based on impact and attrition.

I''m interested to know when sizing a new ball mill, as to why recirculating load has no effect on the power calculation, although it will have effect on volumetric capacity naturally. For instance a mill of 300tph with a 300% recirculating load would have 1200 tph going through effectively, but if

Mill power Usually, plant operators use mill power readings as an indicator 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
