The tower mill calculation is based on the ball mill design sheet but is simplified in that the mill design section is omitted. A simple tower mill factor of 70 allows the mill power to be estimated. MILLCALCv2a 5 19022004. Standard Mill Programmes 4. Conclusion
Generally filling the mill by balls must not exceed 30–35 of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D L D is usually accepted in the range 1.56–1.64.
The geometry of a mill with conical ends is shown in Figure 8.6. The total volume inside the mill is given by Vm 4 D2 mL 1 2Lc L L 1 DtDm 3 1 DtDm 8.16 The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill
Sep 01 2013 A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors including the feed size the product size the mill diameter and the breakage parameters.
previously at a mill stop the measurement of ball charge filling degree could be undertaken and will provide the static media charge angle βstatic 143 . An online measurement of the similar angle βdynamic when the mill is running provides information about the dynamics of the charge. The ratio between the dynamic and the static .
