Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.

In test 3, in which the grid was used to segregate the different sizes of balls, a further advantage of about 4 percent in efficiency is shown. The conical mill in test 4 increased the efficiency to 58 percent more than in test 1. The efficiency with the long (6-foot) conical mill was about the same as with the short (3-foot) one.

The two-stage ball method needs to determine the following parameters: (1) Determination of the diameter of the large ball. It depends on the size of the ball mill, the size of the milled material and the wearability. Generally, the second-order ball diameter in the multi-stage ball is taken as the standard.

Therefore, the influence of ball size distribution on specific selection function can be approached by laboratory tests using single size balls in the mill. For this purpose, Lo and Herbst (1986) have suggested investigations with ball size distribution often used in laboratory tests for scale-up design.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23%
