In the case of placer mining, unconsolidated gravel, or alluvium, is fed into machinery consisting of a hopper and a shaking screen or trommel which frees the desired minerals from the waste gravel. The minerals are then concentrated using sluices or jigs. Large drills are used to sink shafts, excavate stopes and obtain samples for analysis.
A large mining machine has a gearbox speed reduction ratio of 75 from input shaft to output shaft. The gearbox efficiency is known to be 91%. (a) Given that the inertia of the input and output shafts are 50 and 5000 kgm? respectively, calculate the equivalent inertia of the system on both the input and output shafts.
