parameter to isolate ball mill grinding efficiency handicapped efforts to study the effect of any ball mill design or operating variable. Along with plant testing difficulties, only fairly large changes in circuit performance could be linked to a media size change. • Population balance modelling was deemed unsuitable for this purpose.

Alternative design of planetary ball mill Hello, currently I am working on an alternative design of a planetary ball mill. Instead of a normal planetary gear, it should contain a normal gear, and a steel bar with ball bearings that holds the milling jars in place. By this design, I aim to reduce the cost (planetary gears of suitable size are ...

ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding action is caused mainly by particle-particle collisions, so wear to the mill's internals is less of an issue.

Effect of ball charge distributions and mill types on parameter of particles circularity for fine- and coarse-grained feed are shown in Fig. 6(a and b), respectively. As it can be seen, circularity of particles in all tests is higher for OBM than CBM, for both fine- and coarse-grained feeds. The difference of circularity depends on ball mill types.
