Effect of design and operational parameters on particle morphology in
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.

Ball Mill Design
Once you know the ideal speed of rotation for your mill jars, you will need to design your mill around this critical parameter. With most ball mill designs, you have two areas of speed reduction to tweak: from the motor drive shaft to the drive pulley and from the roller bar to the milling jar.

Comparative Study on Improving the Ball Mill Process Parameters
The ball mill process parameters discussed in this study are ball to powder weight ratio, ball mill working capacity and ball mill speed. As Taguchi array, also known as orthogonal array design, adds a new dimension to conventional experimental design, therefore, Orthogonal array (L9) was carefully chosen for experimental design to understand the effects of the ball mill process factors [ 16 ].
