Ball mil design calculation? | Yoo Answers
· The power (in kW) required to turn a ball mill is approximated by: P = d () m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and n is the mill speed, rpm. The actual motor energy consumption is 510% greater than this due to mechanical losses in the motor and gearbox.
