Therefore, the null hypothesis for the Eagle study was tracers do not move through the ball mill at the same rate as coarse particles. Coarse Particles Take Twice as Long. 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.
