At Eagle, the ball milling circuit starts with a crushing plant and ends with a 12.7-mm screen. "The ball mill is 3.20 m diameter and 4.88 m long," the study said. The discharge typically contains "negligible +12.7-mm material." At the time, "tonnage was 45 metric tons per hour (mt/h), and mill power draw was 709 kW," the study said.

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.

Raw powder and solvating media (such as water) are fed into a mill with ceramic balls. This ball mill is then rotated or shaken to create a uniform mixture (called a slurry), with evenly distributed particles of various sizes. Adjustments are made by adding raw powder and binder dispersants throughout this process.
