Center Distance C = (2N + n)/6 This formula is to be used as a guide for the MINIMUM center distance only. The final selection may vary due to: 1.Required clearance dimensions 2.Allowing the final chain length to be an even number of pitches. NOTE: An odd number of pitches requires an offset link, which should be avoided if possible.
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the …
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 …

Aug 28, 2001· In the case of cataracting motion in a ball mill, the center of gravity of the ball charge is deflected horizontally by at least the dynamic angle of repose Θ. At sufficiently high filling degrees, the apex of the bed with κ=Θ+ε may exceed the critical angle κ=90°+ϕ W for centrifuging of a single particle.
Ball mills are predominantly used machines for grinding in the cement industry. Although ball mills ... However in Chamber I at a distance of 2 to 4 meters, around 5 broken/damaged liner plates were observed. • Empty heights of both the chambers measured to calculate the ball charge, % filling and estimate the power consumption at mill shaft ...
• You can calculate the gear ratio by using the number of teeth of the "driving gear" (a.k.a. the inputgear) divided by the number of teeth of the "driven gear" (a.k.a. the outputgear). • We gear up when we increase velocity and decrease torque. Ratio: 3:1
