This is usually performed soon after a crash stop. The basic principle is to measure the height 'H' from the charge to the shell and the internal mill diameter 'Di'. By calculating the ratio 'H/Di' and using the graph below. (Figure 1), the charge filling degree in volume could be estimated. The number of visible.

The calculation of dij includes the aforementioned S and B functions, which can be determined in a laboratory batch mill. However, these parameters are sensitive to milling conditions such as the mill rotational speed, ball filling, powder filling, mill diameter, and ball diameter. Therefore, they must be appropriately corrected.

Apr 4, 2017 . Moly-cop tools for evaluation and optimisation of milling circuits can give/predict a very fair ball size to be used for a specific milling circuit taking into consideration the ore (density, bond work index) and operational parameters(mill speed, mill filling degree and effective diameter). Smaller balls are effective.

Received February 28, 2012; reviewed; accepted March 16, 2012. THE OPTIMAL BALL DIAMETER . grinding quartz and copper ore in a laboratory ball mill, there has been defined a general form of the equation for determining: the optimal ball diameter depending on the grain size being ground; and the parameter of the.

Dec 21, 2017 . A transparent mill (552×180mm), made of Perspex material and filled with 10mm balls, was used for the tests. Ball filling and mill fractional speed were kept constant respectively at 20% and 60% while slurry filling was varied from 0% to 300%. Using a high speed video camera, the motion of the charge was.

size distributions. By combining two software packages the back calculated breakage parameters were used for the prediction of the optimum ball filling volume. The proposed procedure can be also applied for the identification of optimal mill operating parameters for other minerals. Keywords: comminution, breakage rate,.

To calculate the needed grinding work against the grain size changing three half-empirical models are used. These can be related to the Hukki relationship between particle size and the energy required to break the particles. In stirred mills, the Hukki relationship does not apply and instead, experimentation has to be.
