Ball Mill Application and Design. Ball mills are used the size reducing or milling of hard materials such as minerals, glass, advanced ceramics, metal oxides, solar cell and semiconductor materials, nutraceuticals and pharmaceuticals materials down to 1 micron or less. The residence time in ball mills is long enough that all particles getThe starting point for ball mill media and solids charging generally starts as follows: 50% media charge.

A simulation started with the formation of a packed bed of the balls and powders in a still mill (Fig. 1 a).The mill then rotated at a given speed to lift the ball-particle mixtures (Fig. 1 b).After the flow reached the steady state as shown in Fig. 1 c (by monitoring flow velocity), the flow dynamics information was then collected and analysed.

Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal to1.20. C3 is the correction factor for mill diameter and is given as; 𝐶𝐶3 = 2.44 𝐷𝐷 0.2 (3) However, it is important to note that C3 =0.914 vessel used Based on the standard procedure defined by Bond, the ball mill work index is determined by simulating a closed cycle dry grinding in a laboratory Bond ball mill until a stable circulating load of 250% is established (Bond, 1949, Bond, 1952, Bond, 1961).
