design parameters need to be understood. Figure 3: exploded ball mill assembly, computational model Pinion The original design calculations were not available so Principia had to reverse-engineer most of the design (see Figures 3, 5 and 6). This is a common issue when analysing legacy or obsolete equipment. To get the geometry of the mill, a solid
