Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal to1.20. C3 is the correction factor for mill diameter and is given as; 𝐶𝐶3 = 2.44 𝐷𝐷 0.2 (3) However, it is important to note that C3 =0.914 vessel used in …
The filling ratio, ratio of particle to ball and mineral weight were varied to control the mill load. The initial ratio of grading ball was 30 mm: 40 mm: 50 mm: 70 mm = 30: 20: 30: 20. It should be noted that the diameter of instrumented grinding media is 70 mm. Rotation speed of cement ball mill was set to 80%.
