The image above represents shaft power in ball mill length. To calculate shaft power in ball mill length, six essential parameters are needed and these parameters are Value of C, Volume Load Percentage (J), % Critical Speed (Vcr), Bulk Density (s.g), Mill Length (L) and Mill Internal Diameter (D).
The formula for calculating shaft power | ball mill length:
P = 7.33 x C X J X Vcr x (1 – 0.937) x [1 – 0.1/29 – 10Vcr] x s.g. x L x D2.3
Where:
P = Shaft Power | Ball Mill Length
J = Volume Load Percentage
Vcr = % Critical Speed
sg = Bulk Density
L = Mill Length
D = Mill Internal Diameter
Let’s solve an example;
Find the shaft power | ball mill length when the volume load percentage is 8, the %critical speed is 10, the bulk density is 3. the mill length is 14 and the mill internal diameter is 16.
This implies that;
J = Volume Load Percentage = 8
Vcr = % Critical Speed = 10
sg = Bulk Density = 3
L = Mill Length = 14
D = Mill Internal Diameter = 16
P = 7.33 x C X J X Vcr x (1 – 0.937) x [1 – 0.1/29 – 10Vcr] x s.g. x L x D2.3
P = 7.33 x 1 x 8 x 10 x (1 – 0.937) x [1 –Â 0.1/29 – 10(10)] x 3 x 14 x 162.3
Then, P = 36.94 x [1 – 0.1/2-91] x 3 x 14 x 588.133
P = 36.94 x [1 – 0.1/4.038e-28] x 24701.609
P = 36.94 x [1 – 2.47e+26] x 24701.609
So, P = 36.94 x -2.475e+26 x 24701.609
P = -2.259
Therefore, the shaft power | ball mill length is – 2.259 W.
